Property Description: The Project would be located at Coddingtown Mall in northwest Santa Rosa (see Figure 1, Vicinity Map). Coddingtown Mall was constructed in the early 1960s and is located approximately 0.2 mile west of U.S. Highway 101, accessible via the Guerneville Road/Steele Lane interchange. The Project would be constructed on the south side of the mall structure in the space currently occupied by the vacant Gottschalks Department Store and other smaller retail shops. The Project site encompasses approximately 8.11 acres of the 38-acre mall parcel. The site is flat and impervious with the exception of small landscaped areas and trees located in the on-site parking lots. The site is located within the Santa Rosa Urban Service Area and is connected to Santa Rosa’s water and wastewater systems. The property has a General Plan land use designation of Retail and Business Services and is zoned as General Commercial (GC), with the exception of a portion of the parking lot, which is zoned as Office Commercial (CO). Project Description: The Simon Property Group (Applicant) is proposing renovations to a portion of Coddingtown Mall. The renovations would include replacement of the vacant Gottschalks Department Store building and other smaller south-facing retail shops and construction of an approximately 143,487 square-foot single-story Target store. The renovations would also include the two south-facing mall entrances and infrastructure improvements, including construction of new underground utilities, new and reconstructed parking lots, and new landscaping – all within the Project site. No off-site traffic or utility improvements are required for the Project. The Project would require a Conditional Use Permit to be considered by the Santa Rosa Planning Commission and then Design Review, which would be reviewed by the Design Review Board. The Project would also require building and grading permits from the City. If approved, Project construction would take approximately 15 months for completion. Environmental Issues: The Project would result in potentially significant impacts Aesthetics, Air Quality, Biological Resources, Cultural Resources, Geology and Soils, Greenhouse Gases, Hazardous Materials, Hydrology and Water Quality, and Noise. The Project impacts would be mitigated to a less-than-significant level through implementation of recommended mitigation measures or through compliance with existing Municipal Code requirements or City standards. Recommended measures are summarized in the attached Mitigation Monitoring and Reporting Plan (MMRP) and Initial Study/Proposed Mitigated Negative Declaration. The Initial Study/Proposed Mitigated Negative Declaration document has been prepared in consultation with local and state responsible and trustee agencies and in accordance with Section 15063 of the California Environmental Quality Act (CEQA). A 30-day (thirty-day) public review period shall commence on May 10, 2012. Written comments must be sent to the City of Santa Rosa, Community Development Department, Planning Division, 100 Santa Rosa Avenue, Room 3, Santa Rosa CA 95404 by June 12, 2012. The City of Santa Rosa Planning Commission will hold a public hearing on the Initial Study/Mitigated Negative Declaration and Project merits tentatively scheduled for June 14, 2012 in the Santa Rosa City Council Chamber at City Hall (100 Santa Rosa Avenue).

City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 3 GHD Inc. 12506-11-001 1.1 PROJECT LOCATION AND SETTING The Project would be located at the Coddingtown Mall in northwest Santa Rosa (see Figure 1, Vicinity Map). Coddingtown Mall is located approximately 0.2 mile west of U.S. Highway 101, accessible via the Guerneville Road/Steele Lane interchange. The Project would be constructed on the south side of the main mall structure in the space formerly occupied by the Gottschalks Department Store and other smaller retail shops. The Project site encompasses approximately 8.11 acres of the 38-acre mall parcel. Coddingtown Mall currently contains approximately 55 stores, including Macy’s, JC Penney, Whole Foods, Old Navy, and smaller retail and personal service shops. The mall has an existing gross leasable area1 (GLA) of 854,225 square feet and is surrounded by additional detached stores and office buildings. The total existing GLA comprised by the mall and surrounding buildings is 914,027 square feet, with 3,465 parking spaces, for a total of 3.79 parking spaces per 1,000 square feet of GLA. Figure 2, Existing Site Plan, shows the layout of the Coddingtown Mall, including structures, parking, and circulation features. Access to Coddingtown Mall is provided by Guerneville Road/Steele Lane on the north, Cleveland Avenue on the east, Edwards Avenue on the south, and Range Avenue on the west. The Mall as a whole is flat and impervious with the exception of small landscaped areas and trees located in the on-site parking lots. The site is connected to the City’s water and wastewater systems. The property has a General Plan land use designation of Retail and Business Services; it is zoned for General Commercial (GC) uses, with the exception of a portion of the parking lot which is zoned for Office Commercial (CO) uses. 1.2 PROPOSED PROJECT The Simon Property Group (Applicant) is proposing to construct and operate an approximately 143,487 squarefoot retail store, renovate two existing mall entrances, and demolish the former Gottschalks building and other smaller south-facing retail shops (see Figure 2). At this time, this retail space is proposed to be a Target Store. It should be noted that the necessary agreements between Target Stores and the owners of Coddingtown Mall are not yet final, and a different retail tenant could potentially occupy this space. The objectives of the Project are to renovate the Coddingtown Mall to enhance retail activity and to provide a new anchor tenant for the mall to replace the vacant Gottschalks store. On-site improvements would include utility connections, a reconfigured parking lot, lighting, and new landscaping. Table PD-1 shows the proposed modifications to the size of the existing retail space. Table PD-1.

The front of the store would be approximately 490 feet in length, with general building heights ranging from 26 to 35 feet. The tallest feature of the Target building would be an architectural feature with the Target logo at 50 feet in height, located near the eastern edge of the store. The store front would include concrete walkways, landscaping, seating, lighting, spherical bollards, bike racks, cart storage areas, and waste containers. The store’s loading dock area would be on the east side of the building, with space for up to four trucks. Figures 3 through 5 show the existing Gottschalks store fronts with the corresponding Target store elevations. The surface parking lot located to the south of the building site would be reconfigured and would provide 327 parking stalls, including 12 handicap spaces. The reconfigured lot would be interspersed with landscaping, mulched areas, and shade trees, including flowering cherry, raywood ash, crape myrtle, orange sedge, barberry, and Eve Case coffeeberry. Figure 6 shows the proposed parking and landscape plan. Also for fire suppression, the existing 8-inch water line extending through the site from Range Avenue would be upgraded to a 12-inch line. If appropriate easements cannot be secured for the upgrade from Range Avenue, then this fire suppression supply would be provided from a water line in Edwards Avenue to the south. The work associated with this upgrade is anticipated to occur within the periphery of the larger mall site. The Project would result in a net reduction of approximately 21,785 square feet of impervious surfaces at the site (from 344,806 square feet pre-construction to 323,021 square feet post-construction). The reduction in impervious services would result in additional landscaped areas on-site (from 8,280 square feet pre-construction to 30,065 square feet post-construction). In these new landscape areas, the Project would incorporate low impact development (LID) measures in accordance with the City of Santa Rosa’s Standard Urban Storm Water Management Plan (SUSMP). The City’s SUSMP prioritizes the use of LID and the capture of small storm volume for infiltration on-site. The Project’s Preliminary Stormwater Management Plan incorporates the following LID measures into the Project design: vegetated swales; bioretention basins; flow-through planters; and inlet filters. The Project would also renovate two existing mall entries, one to the west of the new Target store near JC Penney and the other to the east near Macy’s. These entry corridors would include new concrete walkways, seating, landscaping, and lighting. The west entry area would include a landscape filtration area to capture and treat storm water runoff. The east entry area would include a new crosswalk and ramps. Existing overhangs would be removed and new swing and sliding doors, screen walls for loading docks, and wood panel signs with the Coddingtown Mall name would be installed. These entry point designs would echo those currently being renovated as part of another project on the north side of the mall. Green technologies and design components to be integrated into the Target store are summarized in Table PD-2.

Construction would be anticipated to begin in July 2012 and continue through September 2013. External construction work would be limited to the hours of 7:00 AM to 5:00 PM, seven days a week. Once the building’s shell is completed, interior construction activities would occur from 7:00 AM to 10:00 PM, as allowed by the City’s Municipal Code Section 17-16.030. The construction process would begin with removal of conflicting above and below-ground infrastructure. Reconstruction of the parking lot would require removal of existing vegetation, including approximately 115 landscape trees. Three existing older trees located within the existing parking lot would be retained and approximately 85 trees would be planted per the Project’s landscape plan (see Figure 6). Stores located immediately adjacent to the demolition area would be temporarily closed during building demolition. Demolition would be performed in a manner to minimize traffic disturbance and utility disruption. As summarized in Table PD-3, demolition would generate a total of approximately 10,460 tons of construction waste, including concrete from footings and floor slabs, metal from building structures, asphalt/concrete from the parking lot, and other miscellaneous construction and demolition debris. Demolition waste diversion would be provided for approximately 88 percent of the demolition waste, which would include off-haul and recycling. Building demolition waste not diverted would be removed and disposed of at a local approved landfill or disposal area. Table PD-3.

City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 12 GHD Inc. 12506-11-001 Site grading would involve excavation for the new building foundation, parking areas, and water line upgrades to ensure adequate fire flow to the site. The existing pavement surface would be removed as necessary for the construction of the building foundation and site improvements. It is estimated that Project construction would disturb approximately 8 acres and would result in the excavation of approximately 3,000 cubic yards of soil. Onsite soils suitable for use as fill would be reused on-site, with any non-suitable soils being disposed of at a local approved landfill or disposal area. Approximately 3,200 net cubic yards of fill material would be needed for site grading. The estimated construction-phase haul volumes and haul truck trips are shown in Table PD-4. Table PD-4. Demolition and Construction Haul Volumes and Haul Truck Trips Material Tons Cubic Yards Haul Truck Trips (20-Cubic Yard Vehicle) Concrete 6,845 3,380 169 Asphalt/Concrete 1,800 950 48 Steel 865 130 6 Miscellaneous Demolition Waste 950 705 35 3,200 160 Demolition Construction Fill --Total Note: 418 The following weight to volume assumptions were used to convert demolition waste from tons to cubic yards: concrete was assumed to weight 150 lbs per cubic foot; asphalt/concrete was assumed to weigh 140 lbs per cubic foot; steel was assumed to weigh 500 lbs per cubic foot; and miscellaneous construction debris was assumed to weigh 100 lbs per cubic foot. Sources: ASCE 7-05 Minimum Design Loads for Buildings and Other Structures; Reade Advanced Materials website: http://www.reade.com/ The number of construction-related vehicles traveling to and from the Project site would vary on a daily basis. During Project demolition and site grading, it is assumed that the peak number of haul trucks expected on any one day would be approximately 8 one-way truck trips per hour, or 64 one-way haul truck trips per day. In addition to haul truck traffic, an average of 40 one-way vehicle trips per day is estimated for the construction crew, with a maximum of 100 one-way vehicle trips per day during peak construction. During construction, a temporary staging area would be established within the parking lot to be reconfigured. The staging area would be used for delivery and storage of building materials and as a contractor parking area. During the estimated 15-month construction period, construction staging would result in a temporary loss of approximately 200 parking spaces. The types of construction equipment that would likely be used during construction are listed in Table PD-5. Table PD-5.

After hours maintenance and stocking would occur between 11:00 PM and 8:00 AM Monday through Saturday and 10:00 PM and 8:00 AM on Sunday. Special holiday hours would occur the week before Thanksgiving through December 26th, with the store open from 4:00 AM to midnight Monday through Saturday and 8:00 AM to midnight on Sunday. The store would be closed on Easter, Thanksgiving Day, and Christmas Day. The workforce for the proposed Target store would consist of approximately 150 to 200 employees. The store’s loading dock area would be located on the east side of the building, with space for up to four trucks. The anticipated electricity, gas, water, and sewer demands of the new Target store are summarized in Table PD-6. Table PD-6. Typical Target Store Service Demands Utility Typical Demand Electricity 187,000 kilowatt hours per month Natural Gas 2,800-3,900 cubic feet per hour Water 3,000 gallons per day (excluding irrigation use) Sewer 3,000 gallons per day Source: Target Developer’s Guide V2.11 Mechanical equipment that could result in operational noise would include rooftop air-conditioning units, rooftop cooling and heating units for the market area, rooftop condenser units, and a trash compactor adjacent to the loading docks. Emergency power would be provided by a natural gas / propane powered 100 kilowatt (approximately 134 horsepower) back-up generator. 1.5 ALTERNATIVES CONSIDERED A design alternative considered for the Project was rotating the Target store footprint 90 degrees from its existing east-west orientation to a north-south orientation. This alternative would have the same footprint as the proposed Target store, however, would have likely required more demolition of the parking lot than the proposed Project. In addition, the east-west orientation of the proposed Project results in more direct access from the parking lot into the Target store entrance and a shorter route for pedestrians walking around the south side of the mall. For these reasons, this alternative was rejected in favor of the site plan shown in Figure 2. 1.6 CEQA REQUIREMENTS This Project is subject to the requirements of the California Environmental Quality Act (CEQA). The CEQA lead agency is the City of Santa Rosa. Prior to making a decision to approve the Project, the City must identify and City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 14 GHD Inc. 12506-11-001 document the potential significant environmental effects of the Project in accordance with CEQA. IS/Proposed MND has been prepared under the direction of the City to fulfill the CEQA requirements. This The purpose of this Initial Study is to provide a basis for deciding whether to prepare an Environmental Impact Report, a Mitigated Negative Declaration or a Negative Declaration. This IS/Proposed MND is intended to satisfy the requirements of the CEQA (Public Resources Code, Div 13, Sec 21000-21177), and the State CEQA Guidelines (California Code of Regulations, Title 14, Sec 15000-15387). CEQA encourages lead agencies and applicants to modify their projects to avoid significant adverse impacts. Section 15063(d) of the State CEQA Guidelines states the content requirements of an Initial Study as follows: 15063(d) Contents. An Initial Study shall contain in brief form: (1) A description of the Project including the location of the Project; (2) An identification of the environmental setting; (3) An identification of environmental effects by use of a checklist, matrix, or other method, provided that entries on a checklist or other form are briefly explained to indicate that there is some evidence to support the entries; (4) A discussion of the ways to mitigate the significant effects identified, if any; (5) An examination of whether the Project would be consistent with existing zoning, plans, and other applicable land use controls; (6) The name of the person or persons who prepared or participated in the Initial Study.

Environmental Effects of the Project Potentially Significant Impact Less-ThanSignificant With Mitigation Incorporation LessThanSignificant Impact No Impact I. AESTHETICS Would the Project: a. Have a substantial adverse effect on a scenic vista? b. Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? c. Substantially degrade the existing visual character or quality of the site and its surroundings? d. Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? Discussion: I. a) Adverse Effect on a Scenic Vista – Less than Significant Impact The Project site is not located on a City-designated scenic road, however, the site would be visible from US Highway 101 (US 101), which the City designates as a scenic road from the northern to southern city limit (Santa Rosa 2009a). In the area of the Project, US 101 is elevated, providing views of scenic vistas to the east and west, though at high vehicular speeds. The site would also be visible from the Fountaingrove Ridge area, located approximately 1.5 miles to the northeast. General Plan Objective T-G seeks to identify, preserve, and enhance scenic roads throughout Santa Rosa in both rural and developed areas. To that end, a number of policies are presented to achieve Objective T-G. Given its purpose, highly developed nature, and proximity to US 101, the one Policy that would apply to this Project would be T-G-10. This policy seeks to ensure any signage along scenic roads does not detract from the area’s scenic character. As the Project would be situated in an existing mall facility – and given its location toward the interior of the mall parcel and away from US 101 – any architectural or other features associated with the Project would not detract from the area’s scenic character along this section of US 101. At the City’s request, a visual simulation was conducted of the Project site as viewed from US 101. The Existing View shown in Figure 7 was taken from the passing lane of US 101 northbound immediately south of the Steele Lane/Guerneville Road interchange. The view looks west toward the southern portion of Coddingtown Mall, showing the Macy’s store to the right in the foreground and the existing Gottschalks building in the background to the left. Parking and mature trees dominate the remainder of the foreground view. The simulated Project View (see Figure 7) presents the same scene, but with the Gottschalks building removed and the proposed Target structure in its place. The mature trees, parking lot, and Macy’s building remain in place. Compared to the Existing View, the proposed structure is lower in profile than the Gottschalks building, with the front of the building situated closer to the primary mall structure than Gottschalks. The proposed structure would increase views across the southern portion of Coddingtown City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 17 GHD Inc. 12506-11-001 Mall to the landscape trees further to the west. Also, it should be noted that, per the City’s General Plan, the critical viewpoint would be from US 101. When seen in passing from US 101, the Target building would be bordered by the Macy’s building and the commercial/office building at the intersection of Cleveland and Edwards avenues to the south, and would occupy only a small part of the field of view. The opportunity for viewing the Project site would be fleeting when traveling at the posted speed limit on US101. Construction activities would have a temporary visual effect during demolition, site grading, and erection of the new building. However, the Project area is located on the southern portion of Coddingtown Mall, partially blocked by existing mall buildings; therefore, construction-related ground disturbance would only be momentarily visible from US 101 The impact to views from US 101 during construction would be less than significant. Following construction, the appearance of the Project site from distant vista points would be similar to the existing views of the mall property as a whole, which is intensively developed as a commercial and office center with multi-story buildings, parking lots, and paved streets. The Project would be located entirely within developed parts of the mall, would be one story instead of two stories of the Gottschalks building, and would be similar in height to adjacent buildings in the mall. The permanent impact to scenic vistas would be less than significant. I. b) Damage State Scenic Resources – No Impact The Project site is located approximately 0.2 mile west of US 101, accessible via the Guerneville Road/Steele Lane interchange. The US 101 corridor within the Project area is not listed as a state designated scenic highway, nor is the corridor listed as an eligible state scenic highway (California Department of Transportation 2011). In addition, no construction work would occur immediately adjacent to or within the US 101 right-of-way. No impact would occur. I. c) Degrade Existing Visual Character – Less than Significant Coddingtown Mall has an E-shaped plan and is surrounded by a large parking lot. The majority of the shopping center is single story, with flat roofs, and features a covered portico. On the exterior, storefronts open directly out to the portico and the parking lots beyond. The simple stucco-clad elevations include wide, open bays defined by square columns and accented by recessed beams across the top of the openings. The three anchor stores [on the east, west, and south] are all essentially two stories with flat roofs and are unified only in their use of tan-colored concrete masonry units at the exteriors. Although focused on the Project site on the south side of the mall, the Existing View in Figure 7 provides a representation of the mall’s visual character. Numerous small buildings line the outer edges of the parking area, mainly south of the shopping center, and a branch library stands at the north parking lot entrance at Guerneville Road. The mall parcel is surrounded on the north, south, and west with a mix of commercial and residential (single- and multi-family) properties. Cleveland Avenue and US 101 form a visual boundary to the east. As described above, the visual character of Coddingtown Mall – including the Project site – is typical of an urban regional mall constructed in the 1960s. For a more thorough description of the mall’s architectural characteristics, please refer to the Project’s Historic Resources Evaluation included in Appendix C. Affected viewers primarily include mall patrons and passers-by on the surrounding streets, as well as motorists on US 101, and single- and multi-family residences to the south along Edwards Avenue. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 18 GHD Inc. 12506-11-001 N NTS CODDINGTOWN MALL PROJECT SITE Existing View Viewpoint & Direction Existing View: View looking west toward the Project site while traveling north in the passing lane of northbound U.S. Highway 101 near the Steele Lane/Guerneville Road exit. This view shows the Project site as it currently exists, with the vacant Gottschalks building. This view was taken on March 2, 2012. Project View: Same view looking west toward the Project site from northbound U.S. Highway 101. This view shows the Project site with a simulation of the completed Target store.

Given the general aesthetic characteristics of the area surrounding the Project site, the visual sensitivity of the site is considered low. Construction would result in temporary construction-related effects on the visual character of the Project site due to demolition, excavation, grading, and erection of the new building. The temporary construction activities and disturbance areas would be visible to adjacent residences, office, and commercial uses. Construction would take approximately 15 months, including 6 months for site demolition and grading, and 9 months for site work and building construction. Construction would also require removal of 115 existing landscape trees within the Project area. Per the Project’s landscape plan (Figure 6), approximately 85 landscape trees would be replanted in the Project site parking area and around the store structure to replace those removed for Project construction. The construction activities described above would have a temporary minor impact on the visual character of the area. However, the construction activities, including the removal of the landscape trees, would not result in a substantial adverse aesthetic impact on the visual character of the site or its surroundings, given the temporary nature of construction, and the presence of other trees onsite that would remain and that would be planted following construction. Therefore, the potential construction-related impact on the visual character of the Project site and its surroundings would be less than significant. Following construction, the appearance of the Project site would not be out of character with the mall property as a whole, which is intensively developed as a commercial and office center with multi-story buildings, parking lots, and paved streets. The Project would be located entirely within already developed parts of the mall and would be similar in height to adjacent buildings. The impact on the visual character of the Project site and its surroundings would be less than significant. I. d) New Source of Light or Glare – Less than Significant with Mitigation The Project would include installation of new exterior lighting, which could create a new source of nighttime light in the Project area. The impact would be significant. Mitigation Measure AES-1: Standards Comply with City of Santa Rosa Outdoor Lighting The Applicant shall comply with the City of Santa Rosa Outdoor Lighting standards contained in Zoning Code Section 20-30.080. These requirements include, but are not limited to, the following: • An outdoor light fixture shall be limited to a maximum height of 14 feet or the height of the nearest building, whichever is less. • New lighting fixtures shall be shielded or recessed to reduce light bleed to adjoining properties, ensuring that the light source is not visible from off the site. • Glare and reflections shall be confined within the boundaries of the Project site to the maximum extent feasible. • Each light fixture shall be directed downward and away from adjoining properties and public rights-of-way, so that no on-site light fixture directly illuminates an area off the site. Compliance with the City’s Outdoor Lighting as required in Mitigation Measure AES-1 would reduce impacts related to new sources of light and glare to a less-than-significant level. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 20 GHD Inc. 12506-11-001 Potentially Significant Impact Less-ThanSignificant With Mitigation Incorporation LessThanSignificant Impact No Impact II. AGRICULTURE AND FOREST RESOURCES Would the Project: (In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Dept. of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In determining whether impacts to forest resources, including timberland, are significant environmental effects, lead agencies may refer to information compiled by the California Department of Forestry and Fire Protection regarding the state’s inventory of forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment Project; and forest carbon measurement methodology provided in Forest Protocols adopted by the California Air Resources Board.) a. Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? b. Conflict with existing zoning for agricultural use, or a Williamson Act contract? c. Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code section 12220(g)), timberland (as defined by Public Resources Code section 4526), or timberland zoned Timberland Production (as defined by Government Code section 51104(g))? d. Result in the loss of forest land or conversion of forest land to non-forest use? e. Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use or conversion of forest land to non-forest use? Discussion: II. a) Convert Farmland – No Impact The California Department of Conservation (CDC), Division of Land Resource Protection, maps important farmlands throughout California. The Project site is mapped as “Urban and Built-Up Land” (CDC 2010), and is not located on or in the vicinity of land mapped as farmland. Based on this, no impact to prime farmland, unique farmland, or farmland of statewide or local importance would occur. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 21 GHD Inc. 12506-11-001 II. b) Conflict with Existing Zoning or Williamson Act Contract – No Impact The California Land Conservation Act (commonly referred to as the Williamson Act) is the state’s primary program for the conservation of private land for agricultural and open space uses. The CDC prepares countywide maps of lands enrolled in Williamson Act contracts. The Project site is not enrolled in the Williamson Act program (PRMD 2011). In addition, the Project site is currently zoned General Commercial (GC) and Office Commercial (CO), neither of which allows agricultural uses. Therefore, the Project site is not located on land zoned for agricultural uses or subject to a Williamson Act contract, and no impact would occur. II. c, d) Conflict with Forestland Zoning – No Impact No land in the Project area is either zoned for forestry or meets the definition of forest land. Thus, neither construction nor operation of the Project would conflict with zoning regulations for forest land, result in the loss of forest land, or result in the conversion of forest land to non‐forest use. No impact would occur. II. e) Convert Farm or Forest Land – No Impact The Project site is located on land designated as urban and built-up land within Santa Rosa’s Urban Growth Boundary and is not located on land used or zoned for agricultural uses. Adjacent properties are designated for commercial/office/residential development and there are no existing agricultural uses in the immediate area. Therefore, the Project would have no impact on conversion of farmland or forest land to non-agricultural or non-forest use. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 22 GHD Inc. 12506-11-001 Potentially Significant Impact Less-ThanSignificant With Mitigation Incorporation LessThanSignificant Impact No Impact III. AIR QUALITY Would the Project: (Where available, the significance criteria established by the applicable air quality management or air pollution control district may be relied upon to make the following determinations.) a. Conflict with or obstruct implementation of the applicable air quality plan? b. Violate any air quality standard or contribute substantially to an existing or projected air quality violation? c. Result in a cumulatively considerable net increase any criteria pollutant for which the Project region is nonattainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? d. Expose sensitive receptors to substantial pollutant concentrations? e. Create objectionable odors affecting a substantial number of people? Discussion: III. a) Conflict with or Obstruct Applicable Air Quality Plan – No Impact The Bay Area Air Quality Management District (BAAQMD) CEQA Air Quality Guidelines (Guidelines)2 set forth criteria for determining a Project’s consistency with the Bay Area 2010 Clean Air Plan (BAAQMD 2011). Per the Guidelines, the BAAQMD considers the Project consistent with the Clean Air Plan if it: 1) can be concluded that a Project supports the primary goals of the Plan [by showing that the Project would not result in significant and unavoidable air quality impacts]; 2) includes applicable control measures from the Plan, and; 3) does not disrupt or hinder implementation of any Plan control measure. The primary goals of the 2010 Clean Air Plan are to protect air quality, public health, and the climate. The Plan includes 55 “control measures” in five categories: stationary and area source; mobile source; transportation control; land use and local impact; and, energy and climate. These control measures are intended to: 2 Reduce emissions and decrease ambient concentrations of harmful pollutants; Safeguard public health by reducing exposure to air pollutants that pose the greatest health risk, with an emphasis on protecting the communities most heavily impacted by air pollution; and, Reduce greenhouse gas (GHG) emissions to protect the climate. On January 9, 2012, the Alameda County Superior Court ruled that the adoption of significance thresholds in the BAAQMD’s CEQA Air Quality Guidelines was a “project” under CEQA, invalidating the thresholds, and required the BAAQMD to conduct the requisite environmental review of the thresholds. This Air Quality section does not rely on any of the previously-adopted thresholds, and therefore is not affected by the court ruling. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 23 GHD Inc. 12506-11-001 As shown in the analyses presented in Impacts III. b., c., d., and e. and VII. a. and b. below, the Project would not result in a significant and unavoidable air quality impact, would not expose the community to greater health risks stemming from exposure to are pollutants, and would assist in reducing GHG emissions. Therefore, the Project would be in support of the primary goals of the Clean Air Plan. No impact would occur. III. b) Violate Air Quality Standard or Contribute Substantially to Existing or Projected Air Quality Violation – Less than Significant Impact The Project site is located in the San Francisco Bay Area Air Basin (Air Basin). The Air Basin is currently designated as a nonattainment area for suspended particulate matter (PM2.5 and PM10) and ozone precursors including reactive organic gases (ROG) and nitrous oxides (NOX). Respirable particulate matter with an aerodynamic diameter of 10 micrometers or less is referred to as PM10. PM2.5 includes a subgroup of finer particles that have an aerodynamic diameter of 2.5 micrometers or less. In the Air Basin, most particulate matter is caused by combustion, factory emissions, construction, grading, demolition, agricultural activities, and motor vehicles. Health effects from particulate matter include reduced lung function, aggravation of respiratory and cardiovascular diseases, increases in mortality rate, and reduced lung function and growth in children. The formation of ozone is through complex chemical reactions between precursor emissions of ROG and NOX in the presence of sunlight. ROG emissions result primarily from incomplete combustion and the evaporation of chemical solvents and fuels. NOX are a group of gaseous compounds of nitrogen and oxygen produced from the combustion of fuels. Health effects from ozone include aggravation of respiratory and cardiovascular diseases, reduced lung function, and increased cough and chest discomfort. Project construction activities would cause exhaust emissions from on-road haul trucks, worker commute vehicles, and off-road heavy duty construction equipment. The BAAQMD has established preliminary screening criteria for both construction and operational phases of a project to provide lead agencies with a conservative indication of whether a proposed project could result in significant air quality impacts. If all of the screening criteria are met by a proposed project, then the lead agency need not perform a detailed air quality assessment of the project’s air pollutant emissions and a less-than-significant impact would occur. Construction The screening criterion3 recommended by the BAAQMD relative to air pollutant emissions (i.e., ROG, NOx, PM2.5, and PM10) for construction activities is 277,000 square feet for a free-standing discount superstore. In comparison, the proposed Target store would be approximately 143,487 square feet in size, which is 133,513 square feet less than the screening criterion for size. The second screening criterion is that the Basic Construction Mitigation Measures identified in the BAAQMD CEQA Air Quality Guidelines be included in the project design and implemented during construction. To meet this requirement, the applicable measures have been included as Mitigation Measure AQ-1 (Basic Construction Measures). The third criterion identifies construction activities (asbestos demolition, multiple construction phases occurring at the same time, extensive site preparation, transport of over 10,000 cubic yards of soil) that 3 The screening criteria to assist in determining whether air pollutant emissions require detailed assessment were not adopted as thresholds by the BAAQMD and, therefore, are not affected by the court ruling discussed in footnote 1. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 24 GHD Inc. 12506-11-001 would preclude a project from a less-than-significant conclusion. Construction activities would include the demolition of the existing Gottschalks building and adjacent retail space. The buildings to be demolished may contain hazardous building materials, such as asbestos-containing materials in the roofing, flooring, ceiling, and piping. The BAAQMD requires the presence of asbestos-containing materials be evaluated in any structure prior to demolition and appropriate pre-demolition notifications. The potential impact to air quality from building demolition is considered significant, given that a hazardous building materials survey has not been completed for the Project, and if present, asbestos containing materials could present an air quality impact if released during construction. Mitigation Measure AQ-1: Basic Construction Measures The Applicant and its Contractor(s) shall implement the Bay Area Air Quality Management District’s Basic Construction Measures, which consist of the following: All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved access roads) shall be watered two times per day. All haul trucks transporting soil, sand, or other loose material off-site shall be covered. All visible mud or dirt track-out onto adjacent public roads shall be removed using wet power vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited. All vehicle speeds on unpaved roads shall be limited to 15 mph. All roadways, driveways, and sidewalks to be paved shall be completed as soon as possible. Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to 5 minutes (as required by the California airborne toxics control measure Title 13, Section 2485 of California Code of Regulations [CCR]). Clear signage shall be provided for construction workers at all access points. All construction equipment shall be maintained and properly tuned in accordance with manufacturer’s specifications. All equipment shall be checked by a certified mechanic and determined to be running in proper condition prior to operation. Post a publicly visible sign with the telephone number and person to contact at the Lead Agency regarding dust complaints. This person shall respond and take corrective action within 48 hours. The Air District’s phone number shall also be visible to ensure compliance with applicable regulations. Mitigation Measure HAZ-1: Hazardous Building Materials Survey and Abatement See Section VIII, Hazards and Hazardous Materials, for a description of this mitigation measure. Mitigation Measure AQ-1 (Basic Construction Measures) would require implementation of the BAAQMD’s basic construction measures in accordance with the BAAQMD Air Quality CEQA guidelines. Mitigation Measure HAZ-1 (Hazardous Building Materials Survey and Abatement) would reduce the impact from demolition activities by requiring pre-construction hazardous materials surveys, abatement practices for any asbestos containing materials in accordance with Cal-OSHA and BAAQMD regulations (Regulation 11, Rule 2), and appropriate BAAQMD notifications prior to commencement of demolition activities. With implementation of the following mitigation measure, the impact would be less than significant. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 25 GHD Inc. 12506-11-001 Operations The screening criterion4 recommended by the BAAQMD relative to air pollutant emissions (i.e., ROG, NOX, PM2.5, and PM10) for operation (i.e., occupancy) of a free-standing discount superstore is 277,000 square feet. The net increase in occupied space would be 69,071 square feet5, which is 17,929 square feet less than the screening size. Therefore, the operational impact would be less than significant. The project would have a less-than-significant impact on CO if it meets the following three screening criteria: The project is consistent with an applicable congestion management program established by a county’s congestion management agency for designated roads or highways, regional transportation plan, and local congestion management agency plans. The project traffic would not increase traffic volumes at affected intersections to more than 44,000 vehicles per hour. The project traffic would not increase traffic volumes at affected intersections to more than 24,000 vehicles per hour where vertical and/or horizontal mixing is substantially limited. As discussed in Transportation/Traffic Impact XVI.b, the Project is consistent with the Sonoma County Congestion Management Program. As discussed in Impact XVI.a and verified in the data in Appendix E, the Project would not increase traffic volumes at affected intersections to more than 44,000 vehicles per hour, or increase traffic volumes at affected intersections to more than 24,000 vehicles per hour. Based on these findings, none of the three screening criteria for CO are exceeded. The Project would, therefore, result in a less-than-significant impact to localized CO concentrations. III. c) Result in Cumulatively Considerable Net Increase of Any Criteria Pollutant for which the Region is in Non-Attainment – Less than Significant Impact As described above, the local Air Basin is in non-attainment for the criteria air pollutants PM2.5 and PM10 and ozone precursors (ROG and NOx). However, the Project meets both the operational and construction screening criteria established by the BAAQMD, and therefore operation of the Project would result in a less-than-significant cumulative impact to air quality from criteria air pollutant and precursor emissions. III. d) Expose Sensitive Receptors to Substantial Pollutant Concentrations – Less than Significant Impact A screening level health risk analysis of Project construction activities was conducted to evaluate construction emissions of diesel particulate matter (DPM) and potential associated health risks on nearby residential areas. A BAAQMD-approved dispersion model was used to predict concentrations of DPM at existing residences near the Project site, and the results were compared to thresholds for excess cancer risk. A copy of the Health Risk Analysis is provided in Appendix B, and the findings are summarized in Table III-1 below. 4 The screening criteria to assist in determining whether air pollutant emissions require detailed assessment was not adopted as a threshold by the BAAQMD, and therefore is not affected by the court ruling discussed in footnote 1. 5 The net increase in occupied space was derived as follows: (143,487 sf of future occupied space - 74,416 sf of existing occupied space = 69,071 sf of new occupied space). Existing occupied space was based on the following environmental baseline conditions (44,416 sf of small shop space occupied + 30,000 sf of the Gottschalks store occupied = 74,416 sf existing occupied space). City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 26 GHD Inc. 12506-11-001 Table III-1. Health Risk Assessment Results for Construction Activities Incremental Child Cancer Risk (1) Incremental Adult Cancer Risk (1) Hazard Index (2) Annual Average PM2.5 (µg/m3) Project 2.4 0.1 0.004 0.02 Threshold 10 10 1.0 0.3 Notes: (1) The incremental child cancer risk is reported as excess cancer cases per million (2) The hazard index is the ratio of the annual DPM concentration to the chronic inhalation reference exposure level The impact of construction-related emissions on sensitive receptors would be less than significant, given that the Project would not expose sensitive receptors to cancer risk or non-cancer disease (represented by the Hazard Index) risk in excess of the threshold for cancer risk from DPM. Project operation would not expose sensitive receptors to substantial pollutant concentrations as the Project does not include any diesel-powered stationary source emissions. Emergency power would be provided by a natural gas- or propane-powered back-up generator, which would not result in DPM emissions. Operational impacts would be less than significant. III. e) Create Objectionable Odors – Less than Significant Impact During construction the various diesel-powered vehicles and equipment could create localized odors. These odors would be temporary and not likely to be noticeable for extended periods of time beyond the construction zone due to atmospheric dissipation. The impact would be less than significant. Project operation would not expose substantial numbers of people to objectionable odors as the Project does not include anything which would cause objectionable odors. No impact would occur. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 27 GHD Inc. 12506-11-001 Potentially Significant Impact Less-ThanSignificant With Mitigation Incorporation LessThanSignificant Impact No Impact IV. BIOLOGICAL RESOURCES Would the Project: a. Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? b. Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations or by the California Department of Fish and Game or US Fish and Wildlife Service? c. Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? d. Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? e. Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? f. Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? Discussion: The Project site is currently a portion of the Coddingtown Mall with a paved parking lot, buildings, and 115 landscape trees. The site is located in the Santa Rosa U.S. Geological Survey (USGS) quadrangle. A California Natural Diversity Database (CNDDB) record search was conducted for the Santa Rosa USGS Quadrangle on April 20, 2012. CNDDB records indicate that no special-status plants or animals have been identified at the site or within ½ mile of the site. Special-Status Species The Project site is urbanized. The site’s existing ornamental landscaping is highly managed and maintained in a busy parking lot and provides little, if any, potential habitat for special-status species. Of the 34 animal species recorded in the CNDDB in the Santa Rosa quandrangle (Santa Rosa 2009b), none have occurrences on the Project site or its surroundings. Recent occurrences of threatened/endangered terrestrial special-status species within the City include northern spotted owl (Strix City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 28 GHD Inc. 12506-11-001 occidentalis caurina) approximately 6 miles east of the Project site, California red-legged frog (Rana draytonii) approximately 7 miles south of the Project site, and California tiger salamander (Ambystoma californiense) approximately 2.5 miles southwest of the Project site (Santa Rosa 2009b). Nonetheless, urbanized areas can provide marginal habitat for special-status bat and bird species. Bats Several bat species may forage in the Project area and roost in buildings or in trees, including the pallid bat (Antrozous pallidus), Townsend’s big-eared bat (Corynorhinus townsendii), western red bat (Lasiurus blossevillii), long-eared myotis (Myotis evotis), long-legged myotis (M. volans), fringed myotis (M. thysanodes), and Yuma myotis (M. yumanensis). These species are former federal species of concern6 and/or California Species of Special Concern. Birds Vegetation at the Project site includes ornamental trees, which can provide roosting and nesting habitat for raptors and other bird species protected under California Fish and Game Codes (Section 3503, Section 3503.5, and Section 3800) and under the Federal Migratory Bird Treaty Act (50 CFR 10.13). IV. a) Impacts to Special-status Species – Less than Significant with Mitigation The Project site and its surroundings is a developed urban habitat primarily covered with impervious surfaces, including buildings and paved parking lots. Onsite vegetation is composed of ornamental trees and landscape vegetation in the site’s parking lots. The recent CNDDB search indicates that no specialstatus plant or animal species have been identified on or in the vicinity of the Project site. The potential for special-status plant and wildlife species to occur at this site or in the area is considered minimal given the lack of habitat or proximity to active commercial urbanization. However, the 115 landscape trees on the Project site, all but three of which would be removed by the Project, may provide nesting habitat for resident and migratory birds protected by the Migratory Bird Treaty Act and California Fish and Game Code. In addition, on-site trees and the exterior eaves of existing buildings to be demolished could provide roosting habitat for bats. Nesting birds could be disturbed by construction noise or tree removal and roosting bats could be disturbed by tree or building removal. This would be a significant impact. Mitigation Measure BIO-1: Conduct Preconstruction Nesting Surveys for Nesting Birds If feasible, the Applicant shall remove trees only between the months of September and January in order to avoid the potential of encountering nesting birds. If tree removal or construction is scheduled to start between February 1 and August 31, a qualified biologist shall conduct preconstruction nesting surveys within 14 days of construction for nesting passerines (small songbirds) and raptors. Trees within a 200-foot radius shall be included in the surveys. If active nests are located in the work area, the qualified biologist shall establish an appropriately-sized buffer around the nest prior to tree removal and/or ground-breaking activities. No construction activity shall occur within the buffer area. To prevent encroachment, the established buffer(s) shall 6 Former Federal Species of Concern are species that were listed by the Sacramento FWS office until 2006, when they stopped maintaining their list. These species are still considered to be at-risk species by other federal and state agencies, as well as various organizations with recognized expertise such as the Audubon Society. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 29 GHD Inc. 12506-11-001 remain in effect until the young have fledged or the nest has been abandoned as confirmed by the qualified biologist. Mitigation Measure BIO-2: Conduct Preconstruction Nesting Surveys for Roosting Bats The Applicant shall ensure that a qualified bat biologist conduct a special-status bat assessment for the trees and building eaves proposed for removal as a result of the Project. The assessment shall occur at least 30 days and no more than 90 days prior to construction activities. If suitable bat habitat is found, a report shall be prepared to detail appropriate mitigation measures for each tree or building eave containing suitable potential or discovered roost habitat (e.g. cavities, crevices, bark or wood fissures, exfoliating bark). Tree and building eave removal shall be conducted in accordance with the report and under supervision of a qualified bat biologist only during the following seasonal periods of bat activity: • August 31 through October 15, when young would be self-sufficiently volant (i.e., able to fly) and prior to hibernation; or • March 1 to April 15, avoiding hibernating bats and prior to formation of maternity colonies. Trees shall be removed in a two-phased removal system conducted over two consecutive days. The first day (in the afternoon), selected limbs and branches not containing cavities are to be removed using only chainsaws (no excavators, etc.). Limbs with cavities, crevices or deep bark fissures shall be avoided, and only branches or limbs without those features shall be removed. On the second day, the remainder of the tree may be removed, either using chainsaws or other equipment. Mitigation Measure BIO-1 (Conduct Preconstruction Nesting Surveys for Nesting Birds) and BIO-2 (Conduct Preconstruction Nesting Surveys for Roosting Bats) would reduce impacts to special-status bird and bat species by scheduling tree removals outside of nesting seasons, requiring pre-construction nesting and roosting surveys as necessary, establishing no work protection zones for active nests, and tree and eave removal procedures. The impact on special-status bird and bat species following mitigation would be less than significant. IV. b, c) Riparian, Sensitive Natural Community, or Wetlands – No Impact The Project site is in an area urban development, primarily covered with impervious surfaces including buildings and paved parking lots. The Project site does not include riparian habitat or other sensitive natural communities, such as grasslands, wetlands (including marsh or vernal pools), or oak woodlands. Therefore, no impact to riparian habitat, federally protected wetlands, or other sensitive natural communities would occur. IV. d) Movement of Fish or Wildlife Species – No Impact The Project site is located in an urbanized area and does not include waterways or other sensitive natural communities, such as grasslands, wetlands, or riparian habitat that provide wildlife movement corridors. Therefore, the Project would not interfere with the movement of native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors. Please refer to Impact IV.a above regarding the potential impacts to nesting birds. No impact would occur movement corridors. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 30 GHD Inc. 12506-11-001 IV. e) Conflict with Local Policies or Ordinances – Less than Significant with Mitigation The Santa Rosa General Plan 2035 contains numerous goals, policies and action items to protect biological resources. The policies include conserving wetlands and waterways so that there is no net loss of wetlands, conserving significant vegetation and trees, and ensuring construction adjacent to creek channels is sensitive to the natural environment. Specific policies relevant to the Project are listed below. OSC-H Conserve significant vegetation and trees. OSC-H-1 Preserve trees and other vegetation, including wildflowers, both as individual specimens and as parts of larger plant communities. OSC-H-2 Preserve and regenerate native oak trees. OSC-H-4 Require incorporation of native plants into landscape plans for new development, where appropriate and feasible, especially in areas adjacent to open space areas or along waterways. The City of Santa Rosa’s tree ordinance effectively applies to any woody plant having a diameter of four inches or more. It also identifies numerous trees, including heritage trees and street trees, which are protected by Santa Rosa City Code Chapter 17-24, Ordinance 2858. Reconfiguration of the existing parking lot, mall entries, and construction of the new Target store would require the removal of approximately 115 existing landscape trees. The majority of the existing landscape trees that would be removed have a breast height diameter ranging from eight- to ten inches. The largest tree to be removed has a breast height diameter of approximately 21-inches. The three largest trees on site (breast height diameters ranging from 45-inches to 50-inches) would not be removed. According to the Project’s landscape plan, 85 trees would be planted within the construction area to replace those removed to accommodate construction. Still, the impact would be significant when considered against the City’s tree ordinance. Mitigation Measure BIO-3: Comply with City of Santa Rosa Tree Ordinance Prior to the issuance of a certificate of occupancy, the Applicant shall comply with the tree replanting requirements indicated in Santa Rosa Municipal Code Chapter 17-24. Replacement trees shall be planted on the Project site; however, if the Project site is inadequate in size to accommodate the replacement trees, the trees shall be planted on public property with the approval of the Director of the City’s Recreation and Parks Department. A fee of $100 per replacement tree may be paid in-lieu of planting replacement trees onsite to the City of Santa Rosa Department of Recreation and Parks. Mitigation Measure BIO-3 (Comply with City of Santa Rosa Tree Ordinance) would reduce potential conflicts to local ordinances protecting biological resources by avoiding or replacing trees in accordance with the City’s tree ordinance standards. The impact following mitigation would be less than significant. IV. f) Habitat Conservation Plan – No Impact No adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan exists for the Project area. No impact would occur. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 31 GHD Inc. 12506-11-001 Potentially Significant Impact Less-ThanSignificant With Mitigation Incorporation LessThanSignificant Impact No Impact V. CULTURAL RESOURCES Would the Project: a. Cause a substantial adverse change in the significance of a historical resource as defined in Section 15064.5? b. Cause a substantial adverse change in the significance of an archaeological resource pursuant to Section 15064.5? c. Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? d. Disturb any human remains, including those interred outside of formal cemeteries? Discussion: V. a) Historical Resources – Less than Significant No buildings or structures within the Project site or the surrounding Coddingtown Mall development are currently listed in the California Register of Historical Places (CRHP) or National Register of Historic Places (NRHP). A historic resource evaluation, included as Appendix C, provides an analysis of the buildings and structures at the Project site and the Coddingtown Mall to determine potential eligibility for future listing in the CRHP or NHRP, and to determine if the Project would have an effect on any potential historical resources. History of Coddingtown Mall The history of Coddingtown Mall is most significantly tied to its namesake and developer, Hugh Codding. Codding was a central character in the postwar development of Santa Rosa and Sonoma County. Hugh purchased land from the Indian Creek Lumber Company at Guerneville Road and Range Avenue, and aspired to create a new commercial development. The shopping center was part of a larger overall development of the area northwest of the downtown, eventually featuring commercial development, residential subdivisions, an industrial park, professional offices, theaters, and an airport. In 1959, Codding had planned on naming the shopping center “Futureland.” The iconic, rotating Coddingtown sign tower is said to have been the first structure installed on the site between 1960 and 1962. The tower, which still stands and is a listed Santa Rosa Landmark, consists of a revolving, neon name plate with “Codding” on one side and “Town” on the other. Welton Beckett and Associates, one of the foremost national firms specializing in the regional shopping center type, was hired to design the shopping center. Construction began in 1962, with the Thrifty Drug Company and Lucky Stores being the first companies to locate in the new development, with several other stores flanked in between. The following year, the last building at the north side was constructed, which housed Roos Atkins, Smith’s and Joseph Magnin – now Sweet River Grill, Bank of the West, Village Sewing, Quizno’s Subs, Baskin Robbins, Pure Beauty, Great Clips and Fresh China. Codding continued work to expand the open air shopping center, and by the mid-1960s, both the Emporium and J.C. Penney agreed to open stores. The Emporium – now a Macy’s Department Store – was constructed City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 32 GHD Inc. 12506-11-001 first and opened with two additional single-story commercial buildings in 1966. J.C. Penney was completed the following year. The buildings at the shopping center remained essentially unchanged until 1979, when the shopping center was enclosed and a third anchor store (Liberty House, later occupied by Gottschalks Department Store) was constructed in 1980. This structure was located on the south side of the shopping center, centered between the two other anchor department stores. The former Liberty House and Gottschalks structure, which was remodeled and expanded in the 1990s, was a stylistic departure from the original shopping center. The rectangular two-story building with a flat roof features a stucco-clad second story that slightly cantilevers out over the split-face tan block-clad first story. At the building’s three exterior entrances, a large glass box extends out over the recessed doorways. Also in 1980, the exterior pedestrian promenades throughout the shopping center were enclosed with rows of clerestory windows, exposed deep wood beams and wood ceilings. The most recent developments at Coddingtown include the demolition of the original Lucky store, and the construction of a new Whole Foods Market in its place; as well as the redesign and construction of two north entrances. Findings The first consideration for determining a property’s eligibility for the CRHP or the NRHP is age. Typically a building must be at least 50 years old, unless special circumstances exist. The Gottschalks building was constructed in 1980 and is only 32 years old. As a result of the research conducted for the historical resource evaluation, no evidence has emerged that the building is of exceptional importance or of any historical importance. It appears to be a typical commercial shopping center structure of its period and does not maintain any historical significance. Therefore, the Gottschalks building is not eligible for listing in the California or National Register of Historical Resources. The buildings of the 1960s original shopping center range in age from 45 to 50 years old. Based on the historical resources evaluation, it appears that the Coddingtown Mall as a whole may have minor significance for its association with the development of northwest Santa Rosa, for its association with Hugh Codding, and as the work of Welton Becket completed in the Modern style. In addition, the sign tower maintains local significance for its association with Hugh Codding and for its style. For a property to qualify as historically significant under either the CRHP or NRHP, it must retain historic integrity of those features necessary to convey its significance. Overall, the Coddingtown Mall property does not retain sufficient integrity to convey its significance given that the original design of the shopping center has been significantly altered over time. For example, the original outdoor pedestrian promenades were enclosed, a new two-story anchor department store was constructed, new entrances have been constructed, facades have been renovated, the original Lucky’s building has been demolished and replaced with a new building, and portions of the original Thrifty Drug store were also partially demolished and replaced with new structures. The single-story commercial buildings retain some of the original design elements, but it appears that the exterior wall cladding has been altered on several buildings and features, such as projecting eaves that have been removed. The only two buildings that appear to retain their integrity of design are the two anchor department stores at the east and west ends of the shopping center (J.C. Penney and Macy’s). The remaining structures have been so extensively altered that the overall property no longer maintains its integrity of material, workmanship, or feeling (i.e., no longer maintains its expression of its period as a whole). Overall, the Coddingtown Mall does not retain its integrity of design, and has been determined to be ineligible for inclusion in the CRHP or NRHP. Only the revolving Coddingtown tower sign, which is a City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 33 GHD Inc. 12506-11-001 listed Santa Rosa landmark, appears to maintain any historical significance. The Project would not result in demolition, relocation, or alteration of the Coddingtown tower sign. The impact on historical resources would be less than significant, given that the Gottschalks Building and the overall Coddingtown Mall is not eligible for inclusion on the CRHP or NRHP, is not included on any other local register of historical resources, and does not maintain any other type of historical significance. V. b,d) Archeological Resources or Human Remains – Less than Significant with Mitigation In order to identify the presence of any known archaeological resources or human remains within the Project area, a records search was conducted at the Northwest Information Center (NWIC) of the California Historical Resources Information System (NWIC 2012). In addition, the State of California Native American Heritage Commission (NAHC) was asked to review the Sacred Lands file for information on Native American cultural resources in the study area, and a list of people responsible for Native American concerns in the area was notified of the proposed Project and asked if they had knowledge of any cultural resources in the Project area. A pedestrian survey of the construction zone was not undertaken for this Initial Study because the presence of impervious surfaces at the Project site prohibits any effective visual surface survey for cultural resources within the area. The NWIC records search did not identify any known cultural resources on the Project site. The nearest recorded sites were architectural historic resource evaluations of off-site residences, located approximately 0.25 mile southwest of the Project’s construction boundary. The NAHC indicated that the record search of the Sacred Lands File did not identify the presence of Native American cultural resources in the Project area (NAHC 2012). A letter was received from a representative of the Federated Indians of Graton Rancheria on March 12, 2012. The letter indicated that the Tribe has no knowledge of cultural resources located in the Project area. An e-mail response was received from a representative of the Mishewal Wappo Tribe of Alexander Valley on March 30, 2012. The representative did not indicate knowledge of cultural resources at the Project site, but noted the need for mitigation should archaeological resources be encountered during construction. No other responses have been received to date. Although there are no known archaeological sites on the Project site, the impact to archaeological resources is considered significant, given the potential for unanticipated discoveries to occur during ground-disturbing construction activities. In addition, the impact to human remains is considered significant, given the potential for unanticipated discoveries to occur during ground-disturbing construction activities. Mitigation Measure CR-1: Cultural Resources Identify and Avoid or Minimize Impacts to Unknown If archaeological materials are encountered during construction activities, the piece of equipment that encounters the materials shall be stopped, and the find inspected by a qualified archaeologist. Project personnel shall not collect cultural materials. If the archaeologist determines that the find qualifies as a unique archaeological resource or a historical resource for purposes of CEQA (CEQA Guidelines Section 15064.5(c)(3)), all work must be stopped in the immediate vicinity to allow the archaeologist to evaluate any materials and recommend appropriate treatment. Such treatment and resolution could include modifying the Project to allow the materials to be left in place, or undertaking data recovery of the materials in accordance with standard archaeological methods. The preferred treatment of the resource is protection and preservation. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 34 GHD Inc. 12506-11-001 Mitigation Measure CR-2: Procedures for Encountering Human Remains California Health and Safety Code Section 7050.5 states that it is a misdemeanor to knowingly disturb a human grave. If human graves are encountered, the Applicant and its Contractor shall ensure that work shall halt in the vicinity and the County Coroner shall be notified. At the same time, a qualified archaeologist shall be contacted to evaluate the situation. If human remains are of Native American origin, the Coroner shall notify the Native American Heritage Commission within 24 hours of identification, pursuant to Public Resources Code 5097.98. Mitigation Measure CR-1 (Identify and Avoid or Minimize Impacts to Unknown Cultural Resources) would reduce the impact to archaeological resources that may be encountered during construction by protecting, preserving, or recovering any significant resources. Mitigation Measure CR-2 (Procedures for Encountering Human Remains) would reduce the impact from discovery of human remains by providing standard procedures in the event that human remains are encountered and requiring adherence to Public Resources Code Section 5097.98 requiring Native American tribal notification. The impact to potentially unknown archaeological resources or human remains following mitigation would be less than significant. V. c) Paleontological or Geological Resources – Less than Significant with Mitigation Paleontological resources are the remains or traces of prehistoric animals and plants. A search of geologic documents and the University of California Museum of Paleontology (UCMP) database was performed for the Project by Kenneth L. Finger, Ph.D., to assess the potential for paleontological resources or paleontologically-sensitive geologic units at the Project site (Finger, 2012). The surficial geology underlying the Project site is mapped as Holocene alluvial fan and fluvial terrace deposits (Qhf) derived primarily from Pleistocene and older sedimentary igneous units (Finger 2012). The hills about one mile northeast of the Project site are mapped as Pliocene-Miocene Petaluma Formation (Tp) and it is most likely that the Petaluma Formation underlies the alluvial deposits at the Project site (Finger 2012). The UCMP database search revealed one Holocene vertebrae fossil and nine Tertiary vertebrae fossil locations in the Petaluma Formation of Sonoma County (Finger 2012). The few specimens recorded indicate the low paleontologic potential of the Petaluma Formation (Finger 2012). Because the surface of the Project area has been heavily disturbed from previous development, it is unlikely that construction-related excavations would encounter much if any of the previously undisturbed Petaluma Formation. Although it is unlikely that Project construction would impact potentially significant paleontological resources, it cannot be ruled out altogether. Therefore, the potential impact is considered significant. Mitigation Measure CR-3: Evaluation and Treatment of Paleontological Resources If paleontological resources (e.g., vertebrate bones, teeth, or abundant and well-preserved invertebrates or plants) are encountered during construction, the Applicant shall ensure work in the immediate vicinity shall be diverted away from the find until a professional paleontologist assesses and salvages the find, if necessary. Mitigation Measure CR-3 (Evaluation and Treatment of Paleontological Resources) would reduce potential impacts to paleontological resources by requiring evaluation and salvage of any paleontological resources found during construction. The impact to paleontological resources following mitigation would be less than significant. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 35 GHD Inc. 12506-11-001 Potentially Significant Impact Less-ThanSignificant With Mitigation Incorporation LessThanSignificant Impact No Impact VI. GEOLOGY AND SOILS Would the Project: Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: a.i. Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42. a.ii. Strong seismic ground shaking? a.iii. Seismic related ground failure, including liquefaction? a.iv. Landslides? b. Result in substantial soil erosion or the loss of topsoil? c. Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the Project, and potentially result in on, or off, site landslide, lateral spreading, subsidence, liquefaction or collapse? d. Be located on expansive soil, as defined in Table 181-B of the Uniform Building Code (1994), creating substantial risks to life or property? e. Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? Discussion: VI. a.i) Fault Rupture – No Impact The Project site is not underlain by a known earthquake fault (Santa Rosa 2009a). The nearest known active fault is the Rodgers Creek fault, located approximately 1 mile east of the Project site. Therefore, no impact from rupture of a known fault would occur. VI. a.ii) Strong Ground Shaking – Less than Significant with Mitigation The USGS estimates that there is a 63 percent probability of a strong earthquake (magnitude 6.7 or higher) occurring on one of the Bay Area faults in the 30-year period between 2007 and 2036, with a 31 percent chance of such an earthquake occurring on the Rodgers Creek fault, the closest fault to the proposed Project (USGS, 2009). As shown in the City’s General Plan, the Project is located in an area that would be subject to violent ground shaking in the event of a major earthquake on the Rodgers Creek City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 36 GHD Inc. 12506-11-001 Fault (Santa Rosa 2009a). The potential impact from strong groundshaking would be significant, given that the shaking could expose people or structures to substantial adverse effects. Mitigation Measure GEO-1: Geotechnical Investigation A California registered Geotechnical Engineer shall conduct a design-level geotechnical study for the Project. The geotechnical study shall evaluate seismic hazards and provide recommendations to mitigate the effect of strong ground shaking; any unstable, liquefiable, or expansive soils; or settlement in adherence with current California Building Code (CBC) standards for earthquake resistant construction. The seismic criteria shall take into account the active faults in the Santa Rosa area and beyond, and ground motions and shaking related to the faults shall be accounted. The geotechnical study shall include evaluation of unstable land in the Project area, including areas susceptible to liquefaction, lateral spreading, or settlement, and areas containing expansive soils. The study shall provide measures to repair, stabilize, or avoid such soils, and include grading, drainage, paving, and foundation design recommendations. The Project shall be designed and constructed in conformance with the specific recommendations contained in the design-level geotechnical study, including recommendations for grading, ground improvement, and foundation support. The recommendations made in the geotechnical study shall be incorporated into the final plans and specifications and implemented during construction. Professional inspection of foundation and excavation, earthwork and other geotechnical aspects of site development shall be performed during construction in accordance with the current version of the CBC. Mitigation Measure GEO-1 (Geotechnical Investigation) would reduce the impact to people and Project structures from strong seismic ground shaking by requiring a comprehensive geotechnical investigation, which would evaluate seismic hazards and provide recommendations to mitigate the effect of strong ground shaking in accordance with CBC construction standards. The impact from strong seismic ground shaking following mitigation would be less than significant. VI. a.iii) Seismic Related Liquefaction – Less than Significant with Mitigation Liquefaction is a phenomenon in which saturated granular sediments temporarily lose their shear strength during periods of earthquake-induced, strong groundshaking. The USGS classifies liquefaction susceptibility according to five categories (from very low to very high) that describe the likely proportion of all liquefaction occurrences that could take place in each category; the abundance or frequency of liquefaction occurrence within the category; the strength of shaking required to produce liquefaction; and the Quaternary-age geologic units included (USGS, 2006). The Project site is located in an area mapped as having moderate liquefaction potential (USGS 2006), which is characterized as requiring groundshaking greater than peak ground acceleration of about 0.1g to 0.2g7 to cause liquefaction (USGS 2006). The potential impact from seismic related liquefaction is considered significant, given the site’s location in an area of moderate liquefaction and strong ground shaking potential. Mitigation Measure GEO-1: Geotechnical Investigation See discussion of VI.a.ii above for a description of this mitigation measure. Mitigation Measure GEO-1 (Geotechnical Investigation) would reduce the impact to people and Project structures from seismic-related liquefaction by requiring a comprehensive geotechnical investigation, 7 The intensity of earthquake-induced ground motions and the potential forces affecting structures within the Project area can be described using peak ground accelerations, which are represented as a fraction of the acceleration of gravity (g). City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 37 GHD Inc. 12506-11-001 which would provide geotechnical measures to repair and stabilize any liquefiable soils in the Project area, in accordance with locally adopted CBC construction standards. The impact from seismic-related liquefaction following mitigation would be less than significant. VI. a.iv) Landslides – No Impact Slope failures and landslides involve the downslope displacement and movement of material, either triggered by static (i.e., gravity) or dynamic (i.e., earthquake) forces. Landslides can occur on slopes of 15 percent or less, but the probability is greater on steeper slopes. In 1998, USGS released a preliminary map and geographic information system (GIS) database that provides a summary of the distribution of landslides evident in the landscape of the San Francisco Bay region (USGS 1998). The Project site is located in an area mapped as flat land, which is defined as areas of gentle slope at low elevation that have little or no potential for the formation of slumps, transitional slides, or earth flows except along stream banks or terrace margins (USGS 1998). Because the Project site is indeed flat, and because it is not located along a stream bank or terrace margin, there would be no impact from landslides. VI. b) Loss of Top Soil – No Impact The Project site is currently comprised of impervious surfaces; the underlying soils would be utilized for on-site grading and as fill as determined suitable. The Project site has been highly altered from its original state and Project grading would not disturb areas with an intact soil profile. Therefore, no substantial loss of topsoil due to erosion or grading is anticipated during construction or operation of the Project, and no impact would occur. Construction impacts to water quality associated with soil erosion are further addressed in Section IX, Hydrology and Water Quality. VI. c) Unstable Soils – Less than Significant with Mitigation Soil surveys performed by the Natural Resources Conservation Service (NRCS) provide information on surface and near-surface soil materials in the Project area. Soil types mapped at the Project site by NRCS include Alluvial land, clayey (AeA) and Zamora silty clay loam (ZaA) (NRCS 2012). According to geologic mapping, these soils are underlain by Holocene alluvial fan and fluvial terrace deposits (Qhf) consisting of gravel, sand, and silt (McLaughlin et. al, 2008). In addition to these mapped units, varying layers of artificial fill would be expected at the site from previous development. The potential impact from lateral spreading is low, because the site is completely flat. Settlement of the ground surface can be accelerated and accentuated by earthquakes. During an earthquake, settlement can occur as a result of the relatively rapid rearrangement, compaction, and settling of subsurface materials (particularly loose, non-compacted, and variable sandy sediments). Areas are susceptible to differential settlement if underlain by compressible sediments, such as poorly engineered artificial fill or bay mud. The potential impact from settlement is considered significant, given the likelihood of varying layers of artificial fill at the site from previous development. As described under Impact VI.a.iv above, the Project site is located on flat land with no threat of landslides. Mitigation Measure GEO-1: Geotechnical Investigation See discussion of VI.a.ii above for a description of this mitigation measure. Mitigation Measure GEO-1 (Geotechnical Investigation) would reduce the impact from unstable soils or geologic units by requiring a comprehensive geotechnical investigation, which would provide geotechnical measures to repair and stabilize any unstable soils in the Project area, including areas susceptible to City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 38 GHD Inc. 12506-11-001 liquefaction, and settlement, in accordance with locally adopted CBC construction standards. The impact from unstable soils or geologic units following mitigation would be less than significant. VI. d) Expansive Soils – Less than Significant Soil types identified at the Project site include Alluvial land, clayey (AeA) and Zamora silty clay loam (ZaA) (NRCS 2012). These soils have a moderate to high shrink swell potential (NRCS 2012). In addition, artificial fills would be expected at the Project site from previous developments. The potential impact from expansive soils is considered significant, given the presence of soils with moderate to high shrink swell potential. Mitigation Measure GEO-1: Geotechnical Investigation See discussion of VI.a.ii above for a description of this mitigation measure. Mitigation Measure GEO-1 (Geotechnical Investigation) would reduce the impact from expansive soils by requiring a comprehensive geotechnical investigation, which would provide geotechnical measures to protect against expansive soils, in accordance with locally adopted CBC construction standards. The impact from expansive soils following mitigation would be less than significant. VI. e) Septic Tanks – No Impact The Project would be connected to the municipal sewer system and would not involve the construction or use of septic tanks or alternative wastewater disposal systems. Therefore, no impact would occur. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 39 GHD Inc. 12506-11-001 Potentially Significant Impact Less-ThanSignificant With Mitigation Incorporation LessThanSignificant Impact No Impact VII. GREENHOUSE GAS EMISS,ONS Would the Project: a. Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? b. Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases? Discussion: Unlike emissions of criteria and toxic air pollutants, which have local or regional impacts, emissions of greenhouse gases (GHGs) contribute to global warming or climate change. Principal GHGs contributing to global warming are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated compounds. These gases allow visible and ultraviolet light from the sun to pass through the atmosphere, but prevent the resulting radiant heat from escaping back into space. Among the potential implications of global warming are rising sea levels, as well as adverse impacts to public health, water supply, water quality, agriculture, forestry, and habitats. In addition, global warming may increase electricity demand for cooling, decrease the availability of hydroelectric power, and affect regional air quality and public health. Like most criteria air pollutants and toxic air contaminants, much of the GHG production comes from motor vehicles. GHG emissions can be reduced to some degree by improved coordination of land use and transportation planning on the city, county, and subregional levels, as well as by other measures to reduce automobile use. Energy conservation measures also can contribute to reductions in GHG emissions (BAAQMD 2011). State of California The State of California has set GHG reduction goals through the passage of Assembly Bill 32 (AB 32), the “Global Warming Solutions Act.” AB 32 aims at reducing GHG emissions to 1990 levels by 2020. The Bay Area Air Quality Management District (BAAQMD) CEQA Air Quality Guidelines (Guidelines) have established GHG thresholds of significance in order to meet the goals of AB 32. The BAAQMD Guidelines8 contain the following thresholds and components: GHG operational thresholds for Land Use projects are: o o o 8 compliance with a Qualified GHG Reduction Strategy; or 1,100 metric tons (MT) of CO2 equivalent (CO2e) per year; or 4.6 MT CO2e per service population (residents plus employees) per year Specific procedures and modeling protocols for quantifying and analyzing GHG impacts; and Methods available to mitigate GHG impacts. On January 9, 2012, the Alameda County Superior Court ruled that the adoption of thresholds in the BAAQMD’s CEQA Air Quality Guidelines was a “project” under CEQA, invalidating the thresholds, and required the BAAQMD to conduct the requisite environmental review of the thresholds. Preparation of this Initial Study began in 2011 prior to the court ruling and the evaluation uses the BAAQMD recommended methodologies and the then-adopted thresholds (i.e., compliance with a Qualified GHG Reduction Strategy; or 1,100 MT of CO2e per year; or 4.6 MT CO2e per service population per year). That evaluation continues to be presented in this document, because the thresholds are a useful tool for determining significance; the evaluation is also supplemented with an assessment that is not reliant upon the now invalidated thresholds. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 40 GHD Inc. 12506-11-001 City of Santa Rosa On December 4, 2001 the Santa Rosa City Council adopted a resolution to become a member of Cities for Climate Protection (CCP), a project of the International Council on Local Environmental Initiatives (now called ICLEI Local Governments for Sustainability). Since that time all eight Sonoma County municipalities and Sonoma County have become members. By becoming a member, local governments commit to completing five milestones: 1) conduct a GHG emissions analysis; 2) set a target for emissions reduction; 3) draft a local action plan for meeting the target; 4) implement the action plan; and 5) monitor and report on the progress (City of Santa Rosa 2002). While the City is currently working through the milestones for municipal operations and GhG emissions, the following discussion focuses on the milestones being completed to address community emissions as this is more pertinent to the Project. In 2005 a community inventory was completed for all of Sonoma County and its communities: Greenhouse Gas Emission Inventory for all sectors of Sonoma County. This inventory was prepared by the Climate Protection Campaign on behalf of the BAAQMD and the Sonoma County Waste Management Agency, and completed the first milestone. The report found that 47 percent of GHG emissions in Sonoma County come from electricity and natural gas usage and 42 percent come from transportation. On August 2, 2005 the City completed the second milestone through the adoption of Resolution 26341 which committed the City to reduce the City's municipal GHG emissions to 20 percent below 2000 levels by 2010, and facilitate community-wide GHG emissions reduction to 25 percent below 1990 levels by 2015 (City of Santa Rosa 2005). The third milestone was completed in October 2008 with the release of Sonoma County Community Climate Action Plan (CCAP), prepared by the Climate Protection Campaign. The CCAP is a guide for the communities in Sonoma County to reduce community greenhouse gas emissions to 25 percent below 1990 levels by 2015. The report found that Sonoma County must reduce its emissions by 1.4 million tons by 2015 to meet the reduction goals. The CCAP outlines a strategy for reaching the goal which includes numerous solutions. The three major solutions would include 4 percent of the reduction coming from energy efficiency, 15 percent coming from increased renewable energy production, and 17 percent coming from transportation. The City is in the process of implementing and developing numerous programs to reduce the City’s community greenhouse gas emissions, and in January 2012, the City issued a Draft Climate Change Action Plan (CAP). Methodology As discussed above, a project that is in compliance with a Qualified GHG Reduction Strategy would be considered less than significant. The City of Santa Rosa’s Draft CAP is not yet considered “qualified” by the BAAQMD; therefore, Santa Rosa’s CAP cannot be used to comply with this threshold. Therefore, the 1,100 MT CO2e per year is used in the following analysis. VII. a) Generation of Greenhouse Gas Emissions – Less than Significant Impact Construction Construction activities that would result in Project-related GHG emissions include exhaust emissions from on-road haul trucks, worker commute vehicles, and off-road heavy duty equipment. BAAQMD has not adopted a threshold for construction-related GHG emissions, but it does suggest determining whether construction GHG emissions would impede meeting AB 32 GHG reduction goals. Project emissions during construction would not be a considerable contribution to the cumulative GHG impact, given that construction would be temporary (approximately 15 months), and the size and nature of construction is not considered to result in significant air quality impacts (for example, the Project is below the BAAQMD City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 41 GHD Inc. 12506-11-001 construction screening criterion for the size of free-standing discount superstores (see Section III, Air Quality). The impact of construction GHG emissions would be less than significant. Operation The BAAQMD has established screening criteria to provide lead agencies with a conservative indication of whether a proposed project could result in significant GHG impacts during operations (i.e., occupancy). If the screening criteria are not exceeded by a proposed project, then the lead agency would not need to perform a detailed GHG assessment of its project’s GHG emissions, and the potential impact would be considered less than significant. The operational screening criterion for GHG for a free-standing discount superstore is 17,000 square feet. As summarized in Section III, Air Quality, the amount of retail space to be demolished would exceed the amount of new retail space to be constructed, resulting in an overall net decrease of 58,144 square feet of retail space. Although there would be a net decrease in overall retail space, the Project would result in an increase in the amount of occupied space (since the Gottschalks building and adjacent stores are not currently 100 percent occupied). Therefore, the net increase in occupied space was determined in order to evaluate if the Project would exceed the operational screening size. The net increase in occupied space would be 69,071 square feet, which is higher than the 17,000 square foot screening size. Therefore, a detailed GHG assessment was conducted. The annual GHG emissions were calculated for the Project using URBEMIS Version 9.2.4 and the BGM Greenhouse Gas Calculator, as recommended by the BAAQMD. Appendix D provides detail for the URBEMIS and BGM estimates. Project emissions are calculated to be approximately 1,327 MT CO2 per year, which is 227 MT CO2 per year more than the 1,100-MT-per-year threshold identified by the BAAQMD Guidelines. The Target Project would meet Cal Green Tier 1 standards, comply with the City’s tree ordinance, increase diversion of construction waste, and execute construction-related reductions such as minimizing equipment idling time and maintaining construction equipment per manufacturers’ specifications. It is noted that these measures also comply with the City’s Draft CAP New Development Checklist currently released for public review. The existing Coddingtown Mall also has components that support the reduction of transportation-related GHG emissions and that would benefit the Target facility as a tenant of Coddingtown Mall. These include bicycle parking, electric vehicle parking, safe access to transit, bus shelters, frequent transit service, and reduced idling at loading docks. In the context of GHG emissions, it is important to note that the Target facility is essentially an infill project in an existing built environment. It would not be a greenfield site on the edge of a City boundary as many such projects are. The site is surrounded by a mix of uses including a substantial amount of residential units (over 1,800 units within ½ mile). Further, there is no other existing Target store north of Highway 12 in Sonoma County. It is reasonable to assume that existing Target customers who live north of the Highway 101/12 interchange (northern Santa Rosa, Wikiup-Larkfield area, Windsor) and shop at the Target Store on Santa Rosa Avenue (located approximately 1.25 miles south of the Highway 101/12 interchange) would now drive the shorter distance to the proposed Target at Coddingtown Mall, resulting in a reduction in vehicle miles traveled (VMT). Another way to evaluate the significance of the Project’s GHG emissions is to compare the Project’s annual emissions to the City’s overall emissions. Santa Rosa’s Draft CAP indicates that GHG emissions for the City as a whole in baseline year 2007 were approximately 1,349,690 MT of CO2. Project operational emissions of 1,327 MT per year would be a negligible part of overall City GHG emissions City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 42 GHD Inc. 12506-11-001 (approximately .09 percent of annual City emission in 2007), and therefore, GHG emissions during operation of the Project would not be a considerable contribution to the cumulative GHG impact. Taking into consideration the Project’s commitments to GHG reduction, existing conditions of the site, and shorter driving distances to a Target Store that would serve northern Sonoma County, the impact on GHG would be less than significant. VII. b) Conflict with an Applicable Plan, Policy, or Regulation – Less than Significant with Mitigation In January 2012, the City issued a Draft CAP. The City’s Draft CAP is not yet adopted; therefore, compliance with the CAP is not evaluated below. There are over 150 policies and programs in the Santa Rosa General Plan that are considered to promote the reduction of greenhouse gas emissions. These policies cover 10 areas: land use and livability, urban design, housing, transportation, public services and facilities, open space and conservation, growth management, economic vitality, historic preservation, and noise and safety (a complete list is shown in the Greenhouse Gas Appendix of the General Plan). Land Use and Livability LUL-A: Foster a compact rather than a scattered development pattern in order to reduce travel, energy, land, and materials consumption while promoting greenhouse gas emission reductions citywide. LUL-I-8 Encourage commercial properties to be retrofitted for energy efficiency and water conservation. The Project would comply with the above land use and livability policies as it would be located within the City’s Urban Growth Boundary in an existing commercial shopping center, and would include integration of green technologies and design components for energy efficiency and water conservation, such as energy management systems, energy efficient heating, cooling, and lighting, white reflective roofs, low flow sensor faucets, plumbing fixtures, and metered plumbing. Urban Design UD-A-12: Promote green building design and low impact development projects. The Project would comply with the above urban design policy because it includes integration of green technologies and design components, such as energy management systems, energy efficient heating, cooling, and lighting, white reflective roofs, low volatile organic compound construction materials, and use of recycled content construction materials, such as recycled steel and Forest Stewardship Council (FSC) wood products. Open Space and Conservation OSC-H: Conserve significant vegetation and trees. OSC-J-1: Review all new construction projects and require dust abatement actions as contained in the CEQA Handbook of the Bay Area Air Quality Management District. OSC-KL: Reduce energy use in existing and new commercial, industrial, and public structures. OSC-K-1: Promote the use of site planning, solar orientation, cool roofs, and landscaping to decrease summer cooling and winter heating needs. Encourage the use of recycled content construction materials. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 43 GHD Inc. 12506-11-001 OSC-K-2: Identify opportunities for decreasing energy use through installation of energy efficient lighting, reduced thermostat settings, and elimination of unnecessary lighting in public facilities. As described in Section IV, Biological Resources, the City of Santa Rosa has numerous trees, including heritage trees and street trees, which are protected by Santa Rosa City Code Chapter 17-24, Ordinance 2858. Reconfiguration of the existing parking lot, mall entries, and construction of the new Target store would require the removal of approximately 115 existing landscape trees, while approximately 85 new trees would be planted, as shown on the Project’s landscape plan (see Figure 6). The three largest trees on site (breast height diameters ranging from 45-inches to 50-inches) would not be removed. Mitigation Measure BIO-1 (Comply with City of Santa Rosa Tree Ordinance) would reduce potential conflicts with policy OSC-H by avoiding or replacing trees in accordance with the City’s tree ordinance standards. Mitigation Measure BIO-3: Comply with City of Santa Rosa Tree Ordinance See Section IV, Biological Resources, for a description of this mitigation measure. Mitigation Measure AQ-1 would reduce potential conflicts with policy OSC-J-1 by requiring the BAAQMD basic construction measures. Mitigation Measure AQ-1: Basic Construction Measures See Section III, Air Quality, for a description of this mitigation measure. General Plan Policies OSC-KL, K-1, and K-2 address the goal of reducing energy use and using recycled content construction materials. The Project would comply with these policies as it would include integration of green technologies and design components, including energy efficiency systems, lighting, diversion of demolition waste, and use of recycled content construction materials, such as recycled steel and Forest Stewardship Council (FSC) wood products. Growth Management GM-A-1: Contain urban development in the Santa Rosa area within the city’s Urban Growth Boundary. The Project would comply with the above growth management policy because it would be located within the City’s Urban Growth Boundary. Economic Vitality EV-C: Promote new retail and higher density uses along the city’s regional/arterial corridors. The Project would comply with the above economic vitality policy because it would be located within an existing commercial shopping center along existing regional arterial corridors. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 44 GHD Inc. 12506-11-001 Potentially Significant Impact Less-ThanSignificant With Mitigation Incorporation LessThanSignificant Impact No Impact VIII. HAZARDS AND HAZARDOUS MATERIALS Would the Project: a. Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? b. Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? c. Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? d. Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? e. For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the Project result in a safety hazard for people residing or working in the Project area? f. For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? g. Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? h. Expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? Discussion: VIII. a) Hazardous Materials – Less than Significant Project construction activities would include the use of hazardous materials, such as fuels, lubricants, paints and solvents. Numerous laws and regulations ensure the safe transportation, use, storage and disposal of hazardous materials. Routine transport of hazardous materials to and from proposed facility sites could result in an incremental increase in the potential for accidents. However, Caltrans and the California Highway Patrol (CHP) regulate the transportation of hazardous materials and wastes, including container types and packaging requirements, as well as licensing and training for truck operators, chemical handlers, and hazardous waste haulers. Because contractors would be required to comply with existing and future hazardous materials laws and regulations covering the transport, use and disposal of City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 45 GHD Inc. 12506-11-001 hazardous materials, the impacts associated with the potential to create a significant hazard to the public or the environment would be less than significant. Following construction, the Target Store would store and sell commercial grade materials with hazardous material components. The use and sale of these materials is common and heavily regulated; therefore, impacts would be less than significant. VIII. b) Accidental Release of Hazardous Materials – Less than Significant with Mitigation Construction activities would include the demolition of the existing Gottschalks building and adjacent stores. The buildings to be demolished may contain hazardous building materials that could present a public health risk during demolition, such as asbestos-containing materials in the roofing, flooring, ceiling, and piping; lead-based paint on the interior and exterior of the buildings; electrical equipment that could contain polychlorinated biphenyls (PCBs); fluorescent light ballasts that could contain di(2-ethylhexyl) phthalate (DEHP) or PCBs; and fluorescent light tubes that contain mercury. The potential impact to the public and environment from hazardous building materials is significant, given that a hazardous building materials survey has not been completed for the Project, and that if present, such materials could present a public health risk if released during construction. Mitigation Measure HAZ-1: Hazardous Building Materials Survey and Abatement Prior to building demolition, the Applicant shall ensure that a registered environmental assessor or a registered engineer perform a hazardous building materials survey. The survey shall be designed to identify any asbestos-containing materials, lead-based paint, electrical equipment containing PCBs, fluorescent lights containing mercury, or fluorescent light ballasts containing PCBs or DEHP. If any friable asbestos-containing materials, lead-containing materials, or other hazardous components of building materials are identified, adequate abatement practices, such as containment and/or removal, in accordance with applicable regulations for the handling and removal of these materials, shall be implemented prior to demolition or renovation. Any PCBcontaining equipment or fluorescent lights containing mercury vapors shall also be removed and disposed of in accordance with applicable regulations. If asbestos is detected, the demolition and removal of asbestos-containing building materials shall be subject to applicable California Occupational Safety and Health Administration (Cal/OSHA) and BAAQMD regulations (Regulation 11, Rule 2). A written plan or notification of intent to demolish buildings shall be provided to the BAAQMD at least ten working days prior to commencement of demolition, even if no ACMs are present. If lead-based paint is identified, then federal and State construction worker health and safety regulations shall be followed during demolition activities, including Title 17 of the CCR, Sections 35001 through 3600. If loose or peeling lead-based paint is identified, it shall be removed by a qualified lead abatement contractor and disposed of in accordance with existing hazardous waste regulations. Mitigation Measure HAZ-1 (Hazardous Building Materials Survey and Abatement) would reduce impacts from hazardous building materials by requiring pre-construction hazardous materials surveys and appropriate abatement and disposal practices prior to demolition. With implementation of mitigation, the impact would be less than significant. VIII. c) Emit Hazardous Emissions within One-quarter Mile of a School – Less than Significant Schools located within 0.25 mile of the Project site include the YWCA - A Special Place Pre-school and The Little Schoolhouse Pre-school. No elementary or high schools are located within 0.25 mile of the City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 46 GHD Inc. 12506-11-001 Project site. Project construction activities would include the use of hazardous materials such as fuels, lubricants, paints and solvents. Routine transport of hazardous materials to and from the Project site could result in an incremental increase in the potential for accidents. However, Caltrans and the CHP regulate the transportation of hazardous materials and wastes, including container types and packaging requirements, as well as licensing and training for truck operators, chemical handlers, and hazardous waste haulers. Because contractors would be required to comply with existing and future hazardous materials laws and regulations covering the transport, use and disposal of hazardous materials, the impacts associated with the potential to create a significant hazard to schools within 0.25 mile of a school would be less than significant. Following construction, the Target Store would store and sell commercial grade materials with hazardous material components, but there would be no new stationary source of hazardous emissions or handling of acutely hazardous materials or waste, therefore, impacts would be less than significant. VIII. d) Included on a List of Hazardous Materials Sites – Less than Significant The Hazardous Waste and Substances Sites List (Cortese List) is a planning document used to comply with CEQA requirements for providing information about the location of hazardous materials release sites. A search of the data resources that provide information regarding the facilities or sites identified as meeting the "Cortese List" requirements was completed to determine if any known hazardous waste facilities exist on or adjacent to the Project site (EPA 2011). No hazardous materials cases were recorded within the construction boundary; however, there are several environmental cases located within 0.25 mile of the Project site. These environmental cases and their potential to affect soil and groundwater conditions in the Project area are summarized in Table VIII-1. Facilities that are permitted to use or store hazardous materials, but have not had a documented release, are not included in the table. Table VIII-1.Hazardous Materials Sites within ¼ Mile of Project Site Environmental Case Name / Address Former EXXON 7-4099 100 Coddingtown Center Approximate Distance from Project Site 850 feet northeast of Project site City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND Regulatory List LUST Environmental Case Summary This facility is an active gas station located at the southwest corner of the intersection of Guerneville Road and Cleveland Avenue. The facility had leaking underground storage tanks that were removed, and cleanup actions included overexcavation of contaminated soil and pumping and treatment of contaminated groundwater. A No Further Action Letter from the Regional Water Board was issued for the site on July 7, 2010, indicating that cleanup had been completed and residual contamination, if any, is low. 47 Potential to Affect Project Low GHD Inc. 12506-11-001 Table VIII-1.Hazardous Materials Sites within ¼ Mile of Project Site Environmental Case Name / Address Approximate Distance from Project Site Regulatory List Cortese Environmental Case Summary Potential to Affect Project Low Goodyear Tire 2021 Cleveland Avenue 500 feet east of Project site This facility included hydraulic lifts and tanks that were removed. Cleanup actions included overexcavation of contaminated soil. A No Further Action Letter from the Regional Water Board was issued for the site on October 24, 2011, indicating that cleanup had been completed and residual contamination, if any, is low. Chevron #9-3762 190 Coddingtown Center 500 feet east of Project site LUST This facility is a former gasoline LUST case site that was closed on July 22, 1993, indicating that cleanup has been completed and residual contamination, if any, is low. Low Raymond Keoki 1052 Edwards Drive <500 feet south of Project site LUST This facility is a former gasoline LUST case site that was closed on July 11, 1990, indicating that cleanup has been completed and residual contamination, if any, is low. Low Goff Property 1945 Cleveland Avenue 750 feet southeast of Project site. Cortese This facility is a former cleanup program site that involved waste oils and hydraulic fluids. The case was closed on May 10, 2006, indicating that cleanup has been completed and residual contamination, if any, is low. Low Boomers Fabricare Center 1321 Guerneville Road 1,300 feet northwest of Project site Cortese This facility is an active dry cleaners site with shallow soil and groundwater contamination. The facility is currently undergoing soil investigation and remediation, which shows residual contamination is mostly localized in shallow soils beneath the building in the area of the former dry cleaning machine. Groundwater gradient recorded in March 2011was towards the west, away from the Project site. Low Source: Cortese List Data Resources, searched January 2012. Note: LUST = Leaking Underground Storage Tank City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 48 GHD Inc. 12506-11-001 None of the sites listed in Table VIII-1 is located immediately adjacent to the Project site. For five of the six listed environmental cases, the regulatory agency has determined that no further action is needed, indicating that cleanup has been completed and residual contamination, if any, is low. For the one active investigation at 1321 Guerneville Road, located approximately 1,300 feet northwest of the Project site, residual contamination is mostly localized in shallow soils beneath the building in the area of a former dry cleaning machine, and the documented groundwater gradient flows towards the west (EGS 2011), which is away from the Project site. These sites are not considered to have impacted the groundwater to the extent of creating a regional groundwater plume that would extend to the area underlying the Project site. The potential to encounter contaminated soil or groundwater at the Project site from these off-site facilities during construction would, therefore, be less than significant. VIII. e, f) Safety Hazard for People Residing or Working Within Two Miles of an Airport – No Impact The nearest public or private airport is Sonoma County Airport, located approximately 5.5 miles northwest of the Project site. The Project site is not located within the referral area or land use plan for the Sonoma County Airport, or within the vicinity of a private air strip. Therefore, no air-traffic related impact would occur. VIII. g) Impair or Interfere with an Adopted Emergency Response/Evacuation Plan – No Impact Project construction would not extend into adjacent roadways and, therefore, would not impair implementation of or physically interfere with any adopted emergency response or evacuation plan routes. Please refer to Section XVI, Transportation, for an analysis of emergency access associated with construction activities. VIII. h) Exposure to Wildland Fires – No Impact The Project site is located on urban land in zones designated as “Non-Fire Hazard” by the California Department of Forestry and Fire Protection (CAL FIRE 2008). Therefore, no wildland fire related impact would occur. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 49 GHD Inc. 12506-11-001 Potentially Significant Impact Less-ThanSignificant With Mitigation Incorporation LessThanSignifica nt Impact No Impact IX. HYDROLOGY AND WATER QUALITY Would the Project: a. Violate any water quality standards or waste discharge requirements? b. Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? c. d. Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on- or off- site? Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off- site? Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff? f. Otherwise substantially degrade water quality? g. Place housing within a 100-year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? h. Place within a 100-year flood hazard area structures which would impede or redirect flood flows? i. Expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam? Inundation by seiche, tsunami, or mudflow? e. j. Discussion: Drainage from the Project site flows west through the City’s storm drain system in a culverted drainage identified in the City’s Citywide Creek Master Plan as Pomo Creek (Santa Rosa 2007). Pomo Creek originates near U.S. Highway 101 near Coddingtown Mall. There is one short stretch above ground at the intersection of Guerneville Road and Range Avenue. The remainder of Pomo Creek is contained within storm drain pipe until it surfaces in Northwest Community Park approximately 1 mile west, flowing through the park before joining Paulin Creek. Paulin Creek is a tributary to Piner Creek; Piner Creek is a tributary to Santa Rosa Creek; and Santa Rosa Creek is a tributary to the Laguna de Santa Rosa, which ultimately flows to the Russian River. The Citywide Creek Master Plan does not identify goals or policies for Pomo Creek (Santa Rosa 2007). City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 50 GHD Inc. 12506-11-001 IX. a, c) Violate Water Quality Standards or Cause Substantial Erosion/Siltation – Less than Significant with Mitigation Project construction would result in approximately 8.11 acres of land disturbance. Construction activities such as excavation, grading, and trenching would temporarily disturb the Project area and could result in erosion if not properly controlled and repaired. Construction could also be a source of chemical contamination from use of alkaline construction materials (e.g., concrete, mortar, hydrated lime) and hazardous or toxic materials, such as fuels. Dewatering of the construction work area could be required if groundwater accumulates in an open trench or excavation area. The discharge of construction dewatering could result in a source of sediment-laden water to the local storm drain system or sanitary sewer if not properly controlled. Therefore, the potential to violate water quality standards and degrade water quality during construction is considered significant. Mitigation Measure HYD-1: Storm Water Pollution Prevention Plan (SWPPP) Prior to construction, the Applicant shall obtain coverage under State Water Resources Control Board Order No. 2009-0009-DWQ, Waste Discharge Requirements for Discharges of Storm Water Runoff Associated with Construction and Land Disturbance Activities. The Applicant shall submit permit registration documents (notice of intent, risk assessment, site maps, SWPPP, annual fee, and certifications) to the State Water Resources Control Board. The SWPPP shall address pollutant sources, best management practices, and other requirements specified in Order 20090009-DWQ. The BMPs shall include any measures included in the erosion and sediment control plans developed for the Project to minimize disturbance after grading or construction. The SWPPP shall also include dust control practices to prevent wind erosion, sediment tracking and dust generation by construction equipment. The Applicant shall ensure that a Qualified SWPPP Practitioner oversees implementation of the SWPPP, including visual inspections, sampling and analysis, and ensuring overall compliance. Mitigation Measure HYD-2: Construction Dewatering If construction dewatering is required, the Applicant shall evaluate reasonable options for dewatering management. The following management options shall be considered: Reuse the water on-site for dust control, compaction, or irrigation. Retain the water on-site in a grassy or porous area to allow infiltration/evaporation. Discharge (by permit) to a sanitary sewer or storm drain (this option may require a temporary method to filter sediment-laden water prior to discharge). If discharging to the sanitary sewer, the Applicant shall obtain a one-time discharge permit from the City of Santa Rosa Utilities Department. Measures may include characterizing the discharge and ensuring filtering methods and monitoring to verify that the discharge is compliant with the City’s local wastewater discharge requirements. If discharging to a storm drain (i.e., surface waters), the Project shall comply with Regional Water Quality Control Board Order No. R1-2009-0045, Waste Discharge Requirements for Low Threat Discharges to Surface Waters in the North Coast Region. This permit would only be required if groundwater is discharged to the storm drain system. In such case, the Applicant shall submit permit registration documents and develop a Best Management Practices/Pollution Prevention plan to characterize the discharge and to identify specific BMPs to control the discharge, such as City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 51 GHD Inc. 12506-11-001 sediment controls to ensure that excessive sediment is not discharged, and flow controls to prevent erosion and flooding downstream of the discharge. Mitigation Measure HYD-1 (Storm Water Pollution Prevention Plan) and HYD-2 (Construction Dewatering) would reduce impacts relative to water quality standards and waste discharge requirements by requiring compliance with applicable permits for discharge of storm water runoff associated with construction and groundwater dewatering. This would include placement of erosion control measures and general site and materials management to reduce soil loss and manage groundwater dewatering. With implementation of mitigation the impact would be less than significant. Refer to Impact IX.d,e,f) for a summary of operation-related impacts. IX. b) Substantially Deplete Groundwater Supplies or Interfere with Groundwater Recharge – Less than Significant During construction, dewatering of the construction work area could be required if groundwater accumulates in an excavation area. Dewatering typically involves pumping water out of the excavation area to lower groundwater levels to the extent needed. No substantial lowering of the local groundwater table would occur from such temporary dewatering; therefore, the impact from construction dewatering is considered less than significant. Following construction, the Project would obtain potable water from the City of Santa Rosa. The City obtains the majority of its water from entitlement from the Sonoma County Water Agency (18,514 acre feet in 2010) and a lesser amount from two active City groundwater wells (902 acre feet in 2010) (Santa Rosa 2011). The Project would increase water demands, but would not result in a substantial effect on the groundwater table or groundwater supplies. In addition, the Project would not interfere with groundwater recharge as the Project site is currently impervious and does not provide groundwater recharge. The operational impact to groundwater supplies would be less than significant. IX. d, e, f) Substantially Increase Runoff Resulting in Flooding, Exceed the Capacity of the Storm Drain System, or Degrade Water Quality – Less than Significant Drainage from the Project site flows west through the City’s storm drain system in a culverted drainage named Pomo Creek. Pomo Creek connects to Paulin Creek at Northwest Community Park, just east of Marlow Road. Paulin Creek is a tributary to Piner Creek; Piner Creek is a tributary to Santa Rosa Creek; and Santa Rosa Creek is a tributary to the Laguna de Santa Rosa, which ultimately flows to the Russian River. Santa Rosa Creek has been listed pursuant to Section 303(d) of the federal Clean Water Act as water-quality impaired for sediment/siltation and temperature (EPA 2010). The Laguna de Santa Rosa is listed as an impaired waterbody for nitrogen, phosphorus, dissolved oxygen, sediment, temperature, mercury, and indicator bacteria (EPA 2010). A Total Maximum Daily Load (TMDL) is a calculation of the maximum amount of a pollutant that a waterbody can receive and still safely meet water quality standards. A TMDL for the Laguna de Santa Rosa has been completed for high levels of ammonia and low dissolved oxygen concentrations, and TMDLs for nitrogen, phosphorus, dissolved oxygen, temperature, and sediment are currently under development. The entire Russian River watershed is impaired for sediment and temperature. Impairments for pathogenic indicator bacteria apply to the Santa Rosa Creek and Laguna de Santa Rosa segments of the watershed. A Sediment TMDL Implementation Policy was adopted in 2004. A TMDL for temperature in the Russian River is currently planned, as is a cleanup plan for pathogens. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 52 GHD Inc. 12506-11-001 As summarized in the Project Description, construction would result in a net reduction of approximately 21,785 square feet of impervious surfaces from the existing condition, with the difference going to new landscaped areas on-site. Following construction, the Project site would include approximately 7.42 acres of impervious area. Runoff from the impervious areas could result in mobilization of oil, trash, landscape chemicals, sediment, and metals in local storm water. Commercial projects in the City of Santa Rosa that create or replace 10,000 square feet or more of impervious area are subject to the City’s Standard Urban Storm Water Mitigation Plan (SUSMP) requirements. The Project is being designed in accordance with the City’s SUSMP Guidelines, which aim to address the impact of development on storm water quality and runoff volume using the basic principles of Low Impact Development (LID) to decentralize storm water treatment and to integrate it into the overall site design. The Project’s Preliminary Stormwater Management Plan includes the use of landscape-based infiltration LID measures that treat and infiltrate storm water as close to the source as possible, including vegetated swales, bioretention basins, and flow-through planters, as well as storm drain inlet filters. By reducing overall impermeable surface areas, increasing surface water infiltration, and minimizing surface water runoff during storm events in accordance with City policies, impacts related to flooding, storm drain capacity, and water quality would be less than significant. IX. g, h) Place Housing and Structures within a 100-Year Flood Zone – No Impact The Project site is not located within a 100-year flood hazard area (Santa Rosa 2009a). Therefore, no impact from a flood hazard area or flood flows would occur. IX. i) Flooding from a Levee or Dam – No Impact The Project site is not located within an inundation zone of a nearby levee or dam (Santa Rosa 2009). No impact would occur. IX. j) Inundation by Seiche, Tsunami, or Mudflow – No Impact The Project site is not located near any isolated bodies of water and would not be subject to inundation by seiche, which are seismically-induced waves in lakes and reservoirs. The Project site and its surroundings are located on flat land and would not be subject to mudflows. The Project site is located over 20 miles from the Pacific Ocean and is not within a tsunami evacuation area, nor would it be subject to potential tsunami impacts (Cal EMA 2009). Therefore, no impact from seiche, tsunami, or mudflows would occur. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 53 GHD Inc. 12506-11-001 Potentially Significant Impact Less-ThanSignificant With Mitigation Incorporation LessThanSignificant Impact No Impact X. LAND USE AND PLANNING Would the Project: a. Physically divide an established community? b. Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the Project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? c. Conflict with any applicable habitat conservation plan or natural community conservation plan? Discussion: X. a) Physically Divide an Established Community – No Impact The Project would replace an existing structure located entirely within a developed site that is surrounded by other development, with no off-site improvements needed. Therefore, the Project would not physically divide an established community. No impact would occur. X. b) Conflict with Applicable Land Use Plans, Policies or Regulations – No Impact The Project is consistent with the existing general commercial and office/commercial development zoning of the property. The Project would also be consistent with the retail/business services land use proposed for the property in the Draft North Santa Rosa Station Area Specific Plan, which has not yet been adopted. No impact would occur. X. c) Conflict with any Applicable Habitat Conservation Plan – No Impact No adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plans exists for the Project area. Therefore, no impact would occur.

MINERAL RESOURCES Would the Project: Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? Result in the loss of availability of a locally-important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan? Discussion: XI. a, b) Result in the Loss of Availability of a Known Mineral Resource of Value to the Region or Delineated by a General Plan, Specific Plan or other Land Use Plan – No Impact The City of Santa Rosa General Plan does not identify any State-designated (MRZ-2) or locally important mineral resource locations in the vicinity of the Project site. Therefore, the Project would not create an adverse impact upon mineral resources.

NOISE Would the Project result in: a. Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? b. Exposure of persons to or generation of excessive ground borne vibration or ground borne noise levels? c. A substantial permanent increase in ambient noise levels in the Project vicinity above levels existing without the Project? d. A substantial temporary or periodic increase in ambient noise levels in the Project vicinity above levels existing without the Project? e. For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the Project expose people residing or working in the Project area to excessive noise levels? f. For a project within the vicinity of a private airstrip, would the Project expose people residing or working in the project area to excessive noise levels? Discussion: XII. a) Exposure to Noise in Excess of Established Standards – Less than Significant Local Noise Standards and Significance Thresholds The following goals and policies established in the Santa Rosa General Plan provide noise standards that are applicable to the proposed Project: Goal NS-B - Maintain an acceptable community noise level to protect the health and comfort of people living, working, and/or visiting in Santa Rosa, while maintaining a visually-appealing community. Policy NS-B-3 - Prevent new stationary and transportation noise sources from creating a nuisance in existing development. Use a comprehensive program of noise prevention through planning and mitigation, and consider noise impacts as a crucial factor in project approval. Policy NS-B-14 – Discourage new projects that have potential to create ambient noise levels more than 5 dBA DNL above existing background, within 250 feet of sensitive receptors. In addition, Chapter 17-16 of the City of Santa Rosa Municipal Code (Ordinance No. 17-16.20) states that “It is unlawful for any person to operate any machinery, equipment, pump, fan, air-conditioning apparatus or similar mechanical device in any manner so as to create any noise which would cause the noise level at the property line of any property to exceed the ambient base noise level by more than five decibels” (Santa Rosa 1989). Table XII-1 presents the ambient base noise levels established in the Municipal City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 56 GHD Inc. 12506-11-001 Code. Although the City Code does not define the acoustical time descriptor such as Leq (the average noise level) or Lmax (the maximum noise level) that is associated with the above limits, a reasonable interpretation of the City Code would identify the ambient base noise level criteria as an average noise level (Leq). To comply with the Code, noise generated by the proposed Target Store would need to be limited to 60 dBA Leq between the hours of 7:00 AM and 10:00 PM, and 55 dBA Leq between the hours of 10:00 PM and 7:00 AM at the adjacent multi-family residences. Table XII-1. City of Santa Rosa Municipal Code – Ambient Base Noise Levels Zone Daytime Level (dBA) Evening Level (dBA) Nighttime Level (dBA) Single-family Residential 55 50 45 Multi-family Residential 55 55 50 Office and Commercial 60 60 55 Intensive Commercial 65 65 55 Industrial 70 70 70 Source: City of Santa Rosa, City of Santa Rosa Municipal Code 17-16.030, 1989 Existing Noise Environment and Sensitive Receptors The existing noise environment at the Project site results primarily from traffic along U.S. Highway 101 (US 101), Cleveland Avenue, Range Avenue, Edwards Avenue, and local traffic on Coddingtown Mall access roadways. Based on the noise monitoring survey, the Project site is currently exposed to noise levels ranging from 58 to 61 dBA DNL9. Typical intermittent maximum noise levels ranged from 65 to 85 dBA Lmax during the daytime and 55 to 75 dBA Lmax during the nighttime. The nearest adjacent residences to the Project site are the Los Robles Apartments, located at their closest point approximately 125 feet south of the proposed Target parking lot. The existing noise levels at the Los Robles Apartments and surrounding areas are primarily due to local and distant traffic, existing activities occurring at Coddingtown Mall, and local residential noise sources, with ambient noise levels of 57 to 58 dBA DNL, and intermittent maximum noise levels ranging from 65 to 85 Lmax during the daytime and 55 to 75 Lmax during the nighttime. Other nearby receptors include office buildings north of Edwards Avenue, located approximately 220 feet south of the parking lot, and residences south of Edwards Avenue, approximately 400 feet south of the parking lot. Pertinent Project Information The predominant operational noise sources associated with the proposed Target Store would include additional parking lot activity, increased truck deliveries and trash collection, additional loading dock activities at the east end of the store, additional rooftop mechanical equipment, and a new trash compactor. Normal business hours would be 8:00 AM to 11:00 PM Monday through Saturday and 8:00 AM to 10:00 PM on Sunday. After-hours maintenance and stocking would occur between 11:00 PM and 8:00 AM Monday through Saturday and 10:00 PM and 8:00 AM on Sunday. Special holiday hours would occur the week before Thanksgiving through December 26th, with the store open from 4:00 AM to midnight Monday 9 DNL (Day-Night Sound Level) represents the average A-weighted noise level during a 24-hour day, obtained after addition of 10 decibels to levels measured in the night between 10:00 PM and 7:00 AM. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 57 GHD Inc. 12506-11-001 through Saturday and 8:00 AM to midnight on Sunday. Thanksgiving Day, and Christmas Day. The store would be closed on Easter, Compatibility of the Project with the Existing Noise Environment The City of Santa Rosa General Plan Land Use Compatibility Standards identify 70 dBA DNL as the “normally acceptable” noise limit for commercial retail uses (Santa Rosa 2009a). At the setback of the proposed Target store, which at its closest point would be approximately 800 feet from the center line of US 101, noise levels would be approximately 59 to 62 dBA DNL. The proposed Target store would therefore be compatible with Santa Rosa’s noise and land use compatibility standards for the noise environment expected on site. The impact would be less than significant. Project Impacts The predominant operational noise sources associated with the proposed Project would include additional parking lot activity, increased truck deliveries and trash collection, additional loading dock activities at the east end of the store, additional rooftop mechanical equipment, and a new trash compactor. The Coddingtown Mall parking lot would continue to be cleaned by a street sweeper in the same manner that it is now; therefore, the Target Store would not increase noise from sweeper trucks. An evaluation of the different operational noise activities of the Project, and the potential effect on adjacent land uses, is provided below. Trucks For the proposed Project, trucks would access the site from the signalized intersection to Coddingtown Mall at Guerneville Road and Cleveland Avenue. Trucks would travel west toward the docking area passing just south of the existing Macy’s Store, approximately 325 feet from the nearest residential property. Truck trips would be subject to store volume and seasonal variations. Target distribution center tractor-trailer trucks deliver 90% of the store merchandise and average approximately 5 to 7 deliveries per week. Target food distribution center refrigerated trucks average approximately 3 to 4 deliveries per week. Therefore, it is expected that the proposed Target store would receive 8 to 11 deliveries per week, or 1 to 2 deliveries per day. Refrigerated trucks unload at the dock for approximately one hour. Receiving dock hours for tractor-trailer trucks from Target distribution centers and contract carriers are typically between 4:00 AM and midnight Monday through Sunday. All Target store locations have a no idling policy that requires diesel truck engines to be turned off after five minutes, and distribution center trucks do not use audible back-up warning signals. In addition to tractor-trailer trucks, the Target Store would receive local carrier and vendor short trucks, vans, mail, and parcel delivery trucks at a rate of approximately 8 to 12 trucks per day. Receiving dock hours for local carriers and vendors are 8:00 AM to midnight, Monday through Friday. Trash and bales of cardboard would likely be picked up about once per week. Low speed truck noise results from a combination of engine, exhaust, and tire noise as well as releases of compressed air associated with truck/trailer air-brakes. The loading dock of the proposed Target Store would be designed to allow heavy-duty trucks to back up to loading bays, with all loading and unloading taking place within the building. The truck docks would be recessed into the ground and will be equipped with rubber gasket seals to reduce noise generated during loading activities. The use of rubberized gasket type seals at the loading bay doors allows little loading noise to escape. Based on field observations at similar facilities, typical loading noise from trailers backed up to rubber gasket seals would be inaudible at a distance of 100 feet. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 58 GHD Inc. 12506-11-001 Heavy Duty Delivery and Trash Collection Trucks Heavy duty truck deliveries and trash collection trucks typically generate maximum noise levels of 70 to 75 dBA Lmax at a distance of 50 feet. Smaller delivery trucks typically generate maximum noise levels of 60 to 65 dBA Lmax at the same distance. The noise level of backup alarms can vary depending on the type of the sound, but maximum noise levels are typically in the range of 65 to 75 dBA Lmax at a distance of 50 feet. Maximum noise levels generated by these types of trucks circulating approximately 325 feet from the nearest residential property are calculated to reach 54 to 59 dBA Lmax. Refrigeration Trucks and Truck Refrigeration Units Maximum noise levels generated by refrigeration trucks are calculated to reach 46 dBA Lmax at the property line of the nearest residences. The truck refrigeration units would typically cycle on for a period of approximately ten to fifteen minutes in order to maintain a set temperature within the freezer and refrigerated trailer. Once the internal temperature is reached, the units shut off for a period of about eight to eleven minutes until the cycle begins again. It is estimated that up to two deliveries from refrigeration trucks could occur per day, that the trucks would each be unloaded over a period of about one hour, and that the refrigeration cycle would turn on for 10 to 15 minutes approximately three times during each onehour unloading period, totaling 60 to 90 cumulative minutes of refrigeration unit noise per day, on average. It is calculated that the operation of the refrigeration units (conservatively assuming an average of 40 minutes of refrigeration unit noise per hour) would result in hourly average noise levels of 44 dBA Leq at the nearest receivers directly to the south. Vendor Trucks Most deliveries by the smaller vendor trucks would not occur at the recessed loading bays but rather at the delivery service doors located adjacent to the main loading dock. Receiving dock hours for local carriers and vendors are 8:00 AM to midnight, Monday through Friday. The maximum noise level generated by unloading activities associated with the vendor trucks would be 49 to 54 dBA Lmax at the nearest receptors to the south. Trash Compactor A trash compactor would be located on the east side of the store adjacent to the proposed loading bays. Trash compactors typically generate maximum noise levels of 50 to 60 dBA Lmax at 50 feet. The trash compactor would be located approximately 400 feet from the nearest residential property to the south. The maximum noise level at the nearest residential property generated by the trash compactor is calculated to be 42 dBA Lmax during operation. Parking Lot Activity Noise associated with the use of the parking lot would include noise sources such as vehicular circulation, car alarms, door slams, and human voices. The nearest residences to the south are located just over 100 feet from the nearest portion of the proposed parking lot. The hourly equivalent noise level resulting from all of these noise-generating activities in a busy parking lot typically ranges from 40 dBA to 50 dBA Leq at a distance of 100 feet from the parking area. Rooftop Mechanical Equipment Rooftop mounted mechanical equipment would include heating, ventilating, and air conditioning equipment, as well as equipment used for refrigeration purposes. Noise from new rooftop equipment was analyzed using the data provided by the project applicant including a typical roof plan showing the equipment locations, building elevations, and equipment sound levels. Noise levels were calculated at a height of five feet above the ground at the property line of the nearest residential land uses and 15 feet City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 59 GHD Inc. 12506-11-001 above the ground to simulate the noise exposure at the two-story residential apartment units. The attenuating effects of distance and rooftop parapet walls (assumed to be a minimum of 3 feet high) were calculated separately for each piece of equipment (or group of equipment where appropriate) and then summed to calculate the total noise level at each receiver. The results of the calculations showed that operational noise levels from new rooftop equipment would result in noise levels of 47 to 49 dBA Leq at a height of five feet above the ground at the property line and 50 to 51 dBA Leq at the nearest two-story residential apartment units. Impact on Ambient Noise Level Table XII-2 summarizes the intermittent maximum noise levels and average noise levels that would be generated by the operational activities described above at the nearest residential property. As summarized in Table XII-2, the combined noise from the Project when the individual noise generating activities are assumed to be active simultaneously is 55 dBA Leq. Not all of these activities would occur at night, so it is reasonable to assume that the nighttime Leq would be somewhat less. The combined noise levels that could be generated by the Project at peak activity would not exceed the 60 dBA Leq limit between the hours of 7:00 AM and 10:00 PM, and the 55 dBA Leq limit between the hours of 10:00 PM and 7:00 AM at the adjacent multi-family residences set by the City’s Noise Ordinance (see Local Noise Standards and Significance Thresholds above). Operational noise associated with the Project would be less at the offices and residences further south because of increased distance from the noise sources and shielding provided by intervening structures. Therefore, operational noise from the Project would not increase noise levels above the City’s noise ordinance limits, and the impact would be less than significant. Table XII-2. Operational Noise Levels Operational Activity Noise Level at Nearest Receptor Heavy Duty Delivery and Trash Collection Trucks 54-59 dBA Lmax Refrigeration Trucks 46 dBA Lmax Vendor Trucks 49-54 dBA Lmax Trash Compactor 42 dBA Lmax Truck Refrigeration Units 44 dBA Leq Parking Lot Activity 40-50 dBA Leq Rooftop Mechanical Equipment 50-51 dBA Leq Combined Average Noise Level, assuming all noise generating sources are active at the same time. 55 dBA Leq Source: Illingworth and Rodkin, 2012 Under General Plan Policy NS-B-14, a significant noise impact to a residential use would occur if the Project increases ambient noise levels by 5 dBA DNL or more. The following discussion addresses the impacts of the Project’s noise generating activities when taken together in terms of average day/night noise levels, or DNL. The City of Santa Rosa General Plan Land Use Compatibility Standards identifies 65 dBA DNL as the “normally acceptable” noise limit for multi-family residential uses (Santa Rosa 2009a). The existing average day/night noise level near the nearest residential land use is 57 to 58 dBA DNL. The combined City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 60 GHD Inc. 12506-11-001 noise from the activities and equipment of the proposed Project was determined to increase the DNL at nearby residences by less than 2 dBA. Since the City’s 65 dBA DNL standard for multi-family residential uses would not be exceeded and the Project would not increase noise levels at the nearest residences by 5 dbA DNL, the overall operational noise impacts associated with the Project would be less than significant. XII. b) Exposure to Groundborne Vibration or Noise – Less than Significant Operation of heavy construction equipment, particularly pile driving and other impact devices such as pavement breakers or blasting, causes groundborne vibration, which can result in effects ranging from annoyance of people to damage of structures. The proposed Project would not include pile driving, blasting, or other types of construction methods that would generate substantial groundborne vibration or groundborne noise levels. Construction activities would include demolition, site preparation work, foundation work, and new building framing and finishing. Major equipment anticipated during project construction would include dozers, graders, rollers, pavers, loaders, track-hoes, cranes, lifts, and dump trucks. If great enough, the energy transmitted through the ground as vibration during operation of this equipment could result in damage to the structural integrity of adjacent shops during building demolition. To assess the potential for structural damage of adjacent buildings associated with groundborne vibration, the vibratory ground motion in the vicinity of the affected structures is measured in terms of peak particle velocity (PPV) in the vertical and horizontal directions (vector sum), typically in units of inches per second (in/sec). For structural damage, the California Department of Transportation uses a vibration limit of 0.5 in/sec PPV for buildings structurally sound and designed to modern engineering standards, 0.3 in/sec PPV for buildings that are found to be structurally sound but where structural damage is a major concern, and a conservative limit of 0.08 in/sec PPV for ancient buildings or buildings that are documented to be structurally weakened. All buildings in the project vicinity are assumed to be structurally sound, but they may or may not have been designed to modern engineering standards. Therefore, this analysis establishes 0.3 in/sec PPV as the significance threshold for construction vibration to avoid damage to buildings from vibration sources. Based on the vibration source levels for Project-related construction equipment, vibration levels would be expected to be 0.2 in/sec PPV or less, which would be below the 0.3 in/sec PPV significance threshold. Therefore, the impact of groundbourne vibration on the structural integrity of adjacent buildings during demolition of the Gottschalks building would be less than significant. IIn areas where vibration would not be expected to cause structural damage, vibration levels may still be perceptible. However, as with any type of construction, this would be anticipated and it would not be considered significant given the intermittent and short duration of the phases that have the highest potential of producing vibration (demolition and use of jackhammers and other high power tools). The impact would be less than significant. XII. c) Substantial Permanent Increase in Ambient Noise – Less than Significant Traffic volume data for thirteen study area intersections, summarized below, were reviewed to calculate the relative increase in traffic noise levels at nearby sensitive land uses that would be attributable to the Project. The study area intersections were as follows: 1. Guerneville Road/Range Avenue 2. Guerneville Road/Steele Lane 3. Guerneville Road/Cleveland Avenue City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 61 GHD Inc. 12506-11-001 4. Steele Lane/US 101 South 5. Steele Lane/US 101 North 6. West Steele Lane/Illinois Avenue-County Center Drive 7. Coddingtown Driveway/Cleveland Avenue 8. Jennings Avenue/Range Avenue 9. Jennings Avenue/Cleveland Avenue 10. Frances Street/Cleveland Avenue 11. College Avenue/Cleveland Avenue 12. College Avenue /US 101 South 13. College Avenue /US 101 North Traffic volumes under the “Existing” and “Existing Plus Project” traffic scenarios for the weekday PM peak hour and the weekend mid-day peak hour were compared as part of the analysis (see Section XVI, Transportation/Traffic for a summary of the traffic volumes). Per General Plan Policy NS-B-14, a noise impact would be identified at noise-sensitive land uses where the noise level increase would be 5 dBA DNL or greater above existing background noise levels. Noise levels from increases in traffic volume along the roadways listed above would increase by 0 to 2 dBA DNL as a result of the project, which is below the 5 dBA DNL limit. The impact would therefore be less than significant. XII. d) Substantial Temporary Increase in Ambient Noise – Less than Significant with Mitigation The City of Santa Rosa does not have quantitative noise limits for construction activities. However, the City’s Municipal Code (Section 17-16.030) limits construction activities to between the hours of 7:00 AM and 10:00 PM, seven days a week. Noise impacts resulting from construction depend on the noise generated by various pieces of construction equipment, the timing and duration of noise generating activities, and the distance between construction noise sources and noise sensitive areas. Noise generated by construction activities would be the greatest during demolition, site grading, and excavation for underground utilities. Typical maximum noise levels from demolition, grading, and excavation activities range from 70 to 90 dBA Lmax at a distance of 50 feet from the source. The typical range of noise levels at a distance of 50 feet from active construction sites would be 65 to 85 dBA Leq. As described in the Project Description, external construction work would be limited to the hours of 7:00 AM to 5:00 PM, seven days a week. Once the building’s shell in completed, interior construction activities would occur from 7:00 AM to 10:00 PM, as allowed in Municipal Code Section 17-16.030. Therefore, the Project would not conflict with the City’s construction hour limits and would not interfere with any nighttime activities normally associated with residential uses, such as sleep interference. The nearest noise sensitive receivers to the existing Gottschalks building to be demolished are located approximately 250 feet away. During grading and paving activities for the parking lot renovation, the nearest residential receivers would be located approximately 115 feet away. Typical hourly average noise levels that would be experienced at the nearest residences to the south would be 51 to 71 dBA Leq during building demolition and 57 to 77 dBA Leq during parking lot renovation. These noise levels would are loud enough to interfere with speech at the nearby multi-family residences. Therefore, construction noise from demolition activities would result in a significant impact. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 62 GHD Inc. 12506-11-001 Construction noise associated with the Project would be less at the nearest residences to the west and further south of Edwards Avenue because of increased distance from the noise source and shielding provided by intervening structures. Construction noise levels received at distant receivers located to the west and south would generally be at or below ambient daytime traffic noise levels generated by Edwards Avenue and Range Avenue. Mitigation Measure NOI-1: Reduce Construction-Related Noise Construction activities shall be conducted in accordance with the requirements of the City of Santa Rosa Municipal Code. Construction noise control measures may include, but would not be limited to the following: All equipment driven by internal combustion engines shall be equipped with mufflers which are in good condition and appropriate for the equipment. The construction contractor shall utilize “quiet” models of air compressors and other stationary noise sources where technology exists. Unnecessary idling of internal combustion engines shall be prohibited. At all times during project grading and construction, stationary noise-generating equipment shall be located as far as practicable from sensitive receptors. All stationary construction equipment shall be placed so that the emitted noise is directed away from sensitive receptors nearest the project site. Construction staging areas shall be established at locations that will create the greatest distance between the construction-related noise sources and noise-sensitive receptors nearest the project site during all project construction. Owners and occupants of residential and non-residential properties located within 300 feet of the construction site shall be notified of the construction schedule in writing. The construction contractor shall designate a “noise disturbance coordinator” who will be responsible for responding to any local complaints about construction noise. The disturbance coordinator would determine the cause of the noise complaint (e.g., starting too early, bad muffler, etc.) and institute reasonable measures as warranted to correct the problem (e.g., to ensure that the measures above are implemented). A telephone number for the disturbance coordinator shall be conspicuously posted at the construction site. Mitigation Measure NOI-1 (Reduce Construction-Related Noise) would reduce impacts at the nearby multi-family residences and other adjacent non-residential uses from temporary construction noise by requiring mufflers, quiet equipment, and proper location and orientation of equipment to reduce construction noise levels. The implementation of Mitigation Measure NOI-1 would be expected to provide up to 5 to 10 dBA of noise reduction at the nearest sensitive receptors during construction. In addition, the duration of exposure to construction noise would vary on a day-to-day basis depending on the specific activities occurring and the equipment necessary to complete the task. As noted above, most people living in suburban or urban environments have accepted that a certain amount of construction activity will take place from time to time and that a reasonable amount of construction is necessary for new projects. Therefore, the temporary increase in ambient noise levels from construction activity following mitigation would be less than significant. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 63 GHD Inc. 12506-11-001 XII. e, f) Exposure of People Residing or Working near an Airport or Private Airstrip to Excessive Noise Levels – No Impact The Project site is not located within an airport land use plan, within two miles of a public airport, or within the vicinity of an active private airstrip. Therefore, no impact from air-traffic related noise would occur.

POPULATION AND HOUSING Would the Project: a. Induce substantial population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? b. Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? c. Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere? Discussion: XIII. a) Induce Substantial Population Growth – No Impact Projects are considered growth-inducing if they provide new housing, new employment, or expand existing infrastructure. The Project would not provide new housing or expand infrastructure. The Project, however, would provide new employment. The workforce for the proposed Target store would consist of 150 to 200 employees. It is anticipated that the new jobs would not result in a significant in-migration of employees who will need to find housing within the Santa Rosa area. The U.S. Bureau of Labor Statistics indicates a Santa Rosa-Petaluma area workforce of 250,700 people, with approximately 22,300 people unemployed, for an unemployment rate of 8.9 percent in December 2011 (Bureau of Labor Statistics 2012). Given the unemployment rate, there would be a sufficient labor pool in the area to fill the number of jobs that would be created by the Project. This new employment would not induce population growth. XIII. b, c) Displace Housing and People – No Impact The Project would replace vacant commercial space at Coddingtown Mall. It would not displace existing housing or people and would not require construction of replacement housing elsewhere. No impact would occur. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 65 GHD Inc. 12506-11-001 Potentially Significant Impact Less-ThanSignificant With Mitigation Incorporation LessThanSignificant Impact No Impact XIV. PUBLIC SERVICES Would the Project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services: a. Fire protection? b. Police protection? c. Schools? d. Parks? e. Other public facilities? Discussion: XIV. a, b) Impacts Associated with New or Altered Fire or Police Protection – No Impact Fire and police protection services would be provided by the City of Santa Rosa. The nearest fire station is located 0.8 mile to the east on Lewis Road. Other fire stations within 1.5 miles of the Project site are located to the north and south along Coffey Lane and Stony Point Road, respectively. The Project site is located within the Santa Rosa Police Beat 1 patrol area. The Project would result in a net reduction in retail space compared to the area currently served, therefore, no additional fire or police personnel or equipment would be necessary to adequately serve the Project. No impact would occur. XIV. c) Impacts Associated with New or Altered Schools – No Impact The Project site is located within the Santa Rosa School District. Pursuant to Senate Bill 50, the Applicant would be required to pay school impact fees established to offset potential impacts on school facilities. Payment of the fees mandated under Senate Bill 50 is prescribed by the statute, with payment of the fees deemed full and complete mitigation. This fee would be assessed when the Project’s building permit would be issued. Therefore, the Project would have no impact to area schools. XIV. d, e) Impacts Associated with New or Altered Parks or Other Facilities – No Impact The Project is not residential in nature and would not require park acquisition or park development fees to be paid. The workforce for the proposed Target store would consist of 150 to 200 employees, which based on current unemployment rates, would not induce population growth that would result in a need for new parks or other facilities (refer to Impact XIII.a above). No impact would occur.

RECREATION Would the Project: a. Increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? b. Include recreational facilities or require the construction or expansion of recreational facilities, which might have an adverse physical effect on the environment? Discussion: XV. a, b) Increase in the Use of Existing Facilities or Development of Recreation Facilities Resulting in Substantial Physical Deterioration – No Impact The Project is not residential in nature and would not require park acquisition or park development. The workforce for the proposed Target store would consist of 150 to 200 employees, which based on current unemployment rates, would not induce population growth that would result in a need for new parks (refer to Impact XIII.a above). Therefore, no impact to existing recreational resources would occur and no impact would occur from construction or expansion of new recreational facilities, as none would be needed for the Project.

TRANSPORTATION/TRAFFIC Would the Project: a. Conflict with an applicable plan, ordinance or policy establishing measures of effectiveness for the performance of the circulation system, taking into account all modes of transportation including mass transit and non-motorized travel and relevant components of the circulation system, including but not limited to intersections, streets, highways and freeways, pedestrian and bicycle paths, and mass transit? b. Conflict with an applicable congestion management program, including, but not limited to level of service standards and travel demand measures, or other standards established by the county congestion management agency for designated roads or highways? c. Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? d. Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? e. Result in inadequate emergency access? f. Conflict with adopted policies, plans, or programs regarding public transit, bicycle, or pedestrian facilities, or otherwise decrease the performance or safety of such facilities? Discussion: The following impact analyses are based on a Traffic Impact Study conducted specific to this Project by Whitlock & Weinberger Transportation, Inc. (W-Trans), dated April 18, 2012. It is included with this Initial Study as Appendix E. XVI. a) Conflict with an Applicable Plan, Ordinance, Policy, or Program Establishing Measures of Effectiveness for the Performance of the Circulation System – Less than Significant The City of Santa Rosa's adopted Level of Service (LOS) Standard is contained in Santa Rosa General Plan 2035. Standard TD-1 states that the City will try to maintain a level of service (LOS) D or better along all major corridors. Exceptions to meeting this standard are allowed where attainment would result in significant environmental degradation; where topography or environmental impacts make the improvement impossible; or where attainment would ensure loss of an area's unique character. The LOSs used in these analyses are defined in the Transportation Research Board’s 2000 Highway Capacity Manual and are summarized in Appendix E. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 68 GHD Inc. 12506-11-001 Although the City’s standard does not specify criteria for intersections, for the purposes of this analysis, a minimum operation of LOS D for the overall operation of signalized intersections was applied as the threshold of significance for the short-term conditions analysis. This Project’s study area consists of the following study intersections as well as the sections of Guerneville Road, Range Avenue, Edwards Avenue, and Cleveland Avenue surrounding the Project site. 1. Guerneville Road/Range Avenue 2. Guerneville Road/West Steele Lane-Coddingtown Driveway 3. Guerneville Road/Cleveland Avenue 4. Steele Lane/US 101 South 5. Steele Lane/US 101 North 6.

College Avenue/Cleveland Avenue 12. College Avenue/US 101 South 13. College Avenue/US 101 North These study intersections are described in detail in Appendix E. In establishing the study area, intersections of streets identified in the Santa Rosa General Plan 2035 as either Regional/Arterial Streets (e.g., Guerneville Road) or Transitional/Collector Streets (e.g., Jennings Avenue) were included. Consideration was given to evaluating the intersections of Edwards Avenue at both Range Avenue and Cleveland Avenue since a minimal amount of Project traffic could use this roadway, but a review of operation based on count data from 2008 for the evening peak hour indicated that these two intersections at either end of the block are currently operating at LOS B or C, well above the minimum threshold of LOS D. Further, a sensitivity analysis indicates that volumes would need to increase by at least 50 percent on all movements for operation to deteriorate to unacceptable levels. Since this preliminary assessment indicated that no improvements would be necessary, it was determined that these two minor intersections did not warrant further study. Volume data was collected for the majority of the intersections in October 2011, though Steele Lane/ County Center Drive/Illinois Avenue and Cleveland Avenue/Coddingtown Drive were counted in February 2012. Counts during both time periods were taken while local schools were in session. Operating conditions during the weekday PM and weekend mid-day peak periods were evaluated as these time periods reflect the highest traffic volumes areawide and for the proposed Project. The evening peak hour occurs between 4:00 and 6:00 PM and typically reflects the highest level of congestion of the day during the homeward bound commute, while the weekend mid-day peak occurs between 12:00 and 2:00 PM. Existing Conditions The Existing Conditions scenario provides an evaluation of current operation based on existing traffic volumes during the PM and Saturday mid-day peak periods. This condition does not include Projectgenerated traffic volumes. Under existing conditions, all 13 study intersections are operating acceptably City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 69 GHD Inc. 12506-11-001 under the applied LOS standard.

(3) LOS = Level of Service. Existing plus Project Conditions For purposes of estimating the number of new trips (i.e., trip generation) that the proposed Project could be expected to generate, the Institute of Transportation Engineers Trip Generation, 8th Edition (2008), was used. This standard reference is used by jurisdictions throughout the country and is based on actual trip generation studies performed at numerous locations in areas of various populations. The trip generation derivations for weekdays and Saturdays are shown in Tables XVI-2 and XVI-3. The Project, including demolition of some of the currently occupied small shops as well as the Gottschalk’s building (a portion of which was occupied when the traffic counts were taken), is expected to increase average weekday traffic by approximately 1,818 daily trips from existing levels, including 138 added trips during the PM peak hour (see Table XVI-2). On Saturdays, the Project is estimated to add an average of City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 70 GHD Inc. 12506-11-001 2,018 new trips per day, with 156 occurring during the mid-day peak hour (see Table XVI-3). These figures were calculated based on the proposed Project’s traffic generation rates as a “free-standing superstore” compared against the existing mall space (i.e., “shopping center”) to be demolished (see Appendix E, beginning page 17).

(4) Occupied at the time of the October, 2011, traffic counts. The pattern used to allocate new Project trips to the street network was based on data contained in the Traffic Impact Study for the North Santa Rosa Station Area Plan, which used the County of Sonoma’s SCTM/07 model. Trip distribution assumptions for the Station Area Plan, which would encompass the Project site, were based on a “Select Zone” model run. The model-generated distribution of trips was combined with knowledge of the roadway network and consideration of current traffic patterns to determine the anticipated distribution of traffic associated with the proposed Project. As shown in Table XVI-4, the 13 study intersections would be expected to continue operating acceptably at the same LOSs upon the addition of Project-generated traffic (presented above in Tables XVI-2 and XVI-3), with the exception of Guerneville Road/Cleveland Avenue. However, this intersection would remain at an acceptable LOS of D. Impacts are similarly expected to be imperceptible at the intersections of Edwards Avenue with Range Avenue and Cleveland Avenue based on the results indicated for the Jennings Avenue intersections.

(3) LOS = Level of Service Future Cumulative Conditions This analysis of Future Cumulative Conditions tiers from the certified Santa Rosa General Plan 2035 Draft Environmental Impact Report (November 3, 2009) and incorporates by reference the General Plan EIR’s traffic analysis for use as the cumulative analysis for the Target Project, as provided for under Sections 15130(d) and 15150 of the CEQA Guidelines. The City’s General Plan EIR State Clearinghouse Number is 2008092114, and the document is available at the Santa Rosa City Hall, 100 Santa Rosa Avenue, in Santa Rosa for public review. The following roadway improvements are listed in the City of Santa Rosa’s General Plan and the City’s Capital Improvement Program (CIP). They are assumed to be complete in the evaluation of this Future Cumulative Conditions analysis. College Avenue Widening – Cleveland Avenue to Morgan Street (Project #1153, funded for year 2013) – Widen College Avenue to provide three westbound through lanes plus bicycle lanes in both directions Install single lane roundabout at Range Avenue/Jennings Avenue Guerneville Road-Steele Lane Corridor Improvements: o Extend the right turn lane on the US 101 southbound off-ramp to a length of 250 feet o At the intersection of Steele Lane/Cleveland Avenue, reallocate the lanes on the northbound approach to Steele Lane to include separate left-turn, through, and right-turn lanes; on the southbound approach add a 100-foot long right turn lane and reallocate the remaining lanes to provide one through and two left-turn lanes; modify the intersection phasing to provide right-turn overlaps and protected left-turn phasing on both Cleveland Avenue approaches The trip generation estimate used to evaluate Existing plus Project conditions above included a deduction for only that portion of the space to be demolished that was occupied and generating trips at the time when traffic counts were taken (i.e., October, 2011). In evaluating Future Cumulative Conditions, the traffic volumes generated by the Project were considered with the full build-out of Coddingtown Mall, as City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 73 GHD Inc. 12506-11-001 contemplated in the General Plan EIR. The General Plan EIR analysis included trips associated with full occupation of the existing space of Coddingtown Mall. With the existing mall space to be eliminated by the Project taken into account, the Project would result in a net decrease in trips during both the weekday PM peak hour and Saturday mid-day peak hour, as compared to what was evaluated in the General Plan EIR. These results are shown in Tables XVI-5 and XVI-6. Table XVI-5.

(3) ksf = thousand square feet City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 74 GHD Inc. 12506-11-001 The General Plan EIR analysis concluded that three arterials in the area of Coddingtown Mall – and included in this analysis – would not meet the City’s LOS standards at General Plan build-out in 2035. These roadways are: College/West College Avenue (AM = LOS F eastbound; PM = LOS D/E westbound) Guerneville Road (AM = LOS E eastbound) Steele Lane (AM = LOS D/E eastbound) The General Plan EIR concluded that the substandard conditions at these intersections would constitute a significant impact. The analysis presented feasible mitigation measures which, along with policy provisions outlined in the General Plan, could be applied to these intersections to ameliorate the impacts. However, due to a lack of an identified funding mechanism(s), the EIR concluded that these impacts would be significant and unavoidable and the City included them in its Statement of Overriding Considerations for the General Plan EIR. However, the Project would actually yield a net reduction in trips generated at Coddingtown Mall under the Future Cumulative Condition, compared to that of the General Plan buildout scenario (i.e., reoccupation of the Gottschalks building) due to the reduction in overall square footage. Therefore, the Project would have a beneficial contribution to future operation of the transportation network in the Project study area, as compared to that reported in the General Plan EIR; however, the 2035 Future Conditions may still exceed LOS standards as identified in the General Plan EIR. The Project’s contribution to this significant cumulative impact would not be cumulatively considerable, because the contribution would, in fact, be a net reduction compared to Future Cumulative Conditions. As noted above, the City of Santa Rosa is also in the process of preparing the [Draft] North Santa Rosa Station Area Specific Plan, which, if adopted, would guide future development of nearly 1,000 acres surrounding the proposed Sonoma-Marin Area Rail Transit (SMART) passenger rail station to be located on Guerneville Road. Coddingtown Mall – and the Project site – is encompassed within this proposed specific plan area. This Specific Plan addresses: potential land uses; station access and circulation and infrastructure; land use regulations; infrastructure development and financing implementation strategies; and design guidelines to encourage transit-oriented development within the Specific Plan area. As with this Project’s analysis of Future Cumulative Conditions, the Specific Plan’s Draft EIR traffic analysis of future conditions was based on the findings of the City’s General Plan EIR. The Traffic Impact Study included with the Draft EIR for the Specific Plan includes full occupation of the former Gottschalk’s building. The results of the Study show that, with proposed circulation improvements, impacts on traffic congestion on City streets would be less than significant (see Appendix E Traffic Impact Study). Because the Target Store would be smaller than the former Gottschalk’s building, and because cumulative impacts with the Specific Plan would be less than significant, the contribution of the Target Store would not be cumulatively considerable (i.e., less than significant). XVI. b) Conflict with an Applicable Congestion Management Program – Less than Significant The Sonoma County Transportation Authority (SCTA) is designated as the Congestion Management Agency for Sonoma County. The four stated goals of the 2009 Transportation Plan are to maintain the system, relieve congestion, reduce emissions, and plan for safety and health. Based on the analyses provided above and in Section III, Air Quality, the Project would comply with these goals. Therefore, no impact would occur. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 75 GHD Inc. 12506-11-001 XVI. c) Result in a Change in Air Traffic Patterns – No Impact The Project has no components that would result in a change in air traffic patterns. No impact would occur. XVI. d) Substantially Increase Hazards due to a Design Feature or Incompatible Use – Less than Significant Access to the Project site would be via existing driveways on Range Avenue, Guerneville Road, Cleveland Avenue, and Edwards Avenue. The Project would be located in the middle of the Coddingtown Mall site and would not physically affect any existing driveways, nor would it involve alteration of any of the approaching roadways. Since no changes to approach and access are anticipated, the Project would have no impact on the geometry or adequacy of existing site accesses and surrounding roadway network. Further, since the Project results in a lower trip generating potential than would be expected with reoccupation of the existing shopping center space, operation of the existing driveways would be positively affected by the reduced traffic demand and opportunity for vehicular conflict. The proposed Project would be located where a large, anchor tenant building currently exists. Because of its smaller footprint, the Project would result in a change to the parking pattern just south of the building. The existing east-west parking aisles will be replaced with north-south aisles, which would match the pattern of the parking fields surrounding this area. This change would improve circulation through the parking lot as all of the parking aisles in the area south of the shopping center would be in the same direction. No other changes to the site’s existing circulation patterns are expected as a result of the Project. The collision histories from 2008-10 for the study intersections were reviewed to determine any trends or patterns that may indicate a safety issue. A detailed discussion of the collision history analysis is presented in the Project’s Traffic Impact Study (Appendix E) and is summarized here. With the exception of Guerneville Road at Range Avenue and Steele Lane at U.S. Highway 101 (US 101) North, all of the study intersections were determined to have experienced collisions at a lower rate than the Statewide average for similar facilities. With five different primary collision factors among the 19 collisions and seven different approach direction combinations at the Guerneville Road/Range Avenue intersection, no particular pattern is apparent. It is noted that a fatal pedestrian crash and a bicycle-involved crash occurred at this intersection in 2009. The City completed a project during the summer of 2011 that reduced the length of the crossing on the east leg; this Project would be expected to have a positive impact on pedestrian safety. With regard to the Steele Lane/US 101 North ramp, the collision data did not differentiate between the northbound and southbound ramps. Therefore, the elevated number of collisions on the northbound ramp was attributed to the assignment of data based on direction of movement and type of crash. Based on that, the Steele Lane/US 101 North ramp exceeded the Statewide average. The recently-completed US 101 Widening project added capacity which is expected to help reduce congestion-related crashes that occur at this location. The study intersections of Guerneville Road/Range Avenue and Steele Lane/US 101 North Ramps experienced collisions at a rate higher than the statewide average for intersections with similar configurations and controls. The intersection of Guerneville Road/Range Avenue has recently been upgraded to reduce pedestrian crossing time, which improves conditions at this location. The recent US 101 Widening project added capacity that can be expected to reduce the congestion-related types of crashes that occur at this location. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 76 GHD Inc. 12506-11-001 The Project would result in no changes to site access and the surrounding roadway network. In addition, the Project would improve site circulation by re-orienting the parking field south of the Project building to match the fields surrounding it. Therefore, it would have a less-than-significant impact. XVI. e) Result in Inadequate Emergency Access – Less than Significant The Traffic Impact Study included in Appendix E indicates that the Project would result in minimal increases in average delay at intersections surrounding the site, so emergency response times would generally be increased by only a few seconds. Under long-range conditions, however, the Project would actually reduce the volume of traffic that would be generated by the site, providing a beneficial effect on emergency response times. There are no other changes contemplated as part of the Project that would affect emergency access. Therefore, the Project would have a less-than-significant impact on emergency access. XVI. f) Conflict with Adopted Policies, Plans, or Programs Regarding Public Transit, Bicycle, or Pedestrian Facilities, or Otherwise Decrease the Performance or Safety of Such Facilities – Less than Significant Following is a summary of the pedestrian, bicycle, and public transit facilities in the vicinity of, and which could be affected by, the Project. These facilities, and the Project’s potential impacts to these facilities, are discussed in detail in the Project’s Traffic Impact Study found in Appendix E. Pedestrian and Bicycle Facilities Existing sidewalks, curb ramps, and marked crosswalks are provided at intersections surrounding the Project site. Sidewalks also exist along the perimeter of existing buildings at the Coddingtown Mall site and would be extended to provide full connectivity of pedestrian facilities serving the Project and the existing shopping center. A variety of existing bikeways are provided in the vicinity of the Project, facilitating both north-south and east-west access. Further, Santa Rosa’s 2011/12 Capital Improvement Plan (CIP), Bicycle and Pedestrian Master Plan, and Citywide Creek Master Plan include the following projects and/or programs affecting pedestrian and bicycle circulation within the study area: SMART Path Phase 3 Jennings Avenue to Guerneville Road (currently unfunded, included in the Bicycle and Pedestrian Master Plan) – Constructs a portion of the SMART multi-user path along the rail corridor Jennings Avenue Rail Crossing (funding approved for environmental and pre-design) – Pedestrian and bicycle crossing of the SMART rail tracks Highway 101 Bike/Pedestrian Overcrossing (funding approved for Caltrans Project Initiation Document only) - Priority #1 in the Bicycle and Pedestrian Master Plan; pedestrian and bicycle overpass linking the Santa Rosa Junior College area with the Coddingtown Mall area Improve Transit and Shuttle Service on the east side of Range Avenue at Coddingtown Mall to include offstreet stops and a bus turnaround area The Target Store would not conflict with any of plans or programs for pedestrians or bicycles. Existing and planned pedestrian facilities and bikeways in the vicinity of the proposed Project would provide a variety of access options for pedestrians and bicyclists traveling to and from the Project site. The presence of the Project would not deteriorate, or detract from, these facilities. Therefore, the Project would have a less-than-significant impact. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 77 GHD Inc. 12506-11-001 Transit Facilities The Project is located within a short walking distance of the transit hub at Coddingtown Mall, which is along Range Avenue near the J. C. Penney’s store. The hub is served by CityBus Routes 7, 10, 11 and 15, so the site is accessible via transit. It is anticipated that future transit demand generated by the Project could be accommodated by the existing transit routes, as well as the SMART passenger rail service planned for 2016. The North Santa Rosa Station would be located about 0.5 mile to the west of the Project site on Guerneville Road and could serve both employees and customers. The Target Store would not conflict with any of plans or programs for pedestrians or bicycles. Existing and planned future transit services are expected to adequately serve the Project site.

UTILITIES AND SERVICE SYSTEMS Would the Project: a. Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? b. Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? c. Require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? d. Have sufficient water supplies available to serve the Project from existing entitlements and resources, or are new or expanded entitlements needed? e. Result in a determination by the wastewater treatment provider which serves or may serve the Project that it has adequate capacity to serve the Project’s projected demand in addition to the provider’s existing commitments? f. Be served by a landfill with sufficient permitted capacity to accommodate the Project's solid waste disposal needs? g. Comply with federal, state, and local statutes and regulations related to solid waste? Discussion: XVII. a, b, d, e) Exceed Applicable Wastewater Treatment Requirements and Capacity, or Require Construction or Expansion of New Water or Wastewater Treatment Facilities – No Impact The Project is located within the Santa Rosa Urban Service Area. Wastewater from the Project would be conveyed to the City’s Laguna Subregional Water Reuse Facility (Laguna Plant) for treatment. The Laguna Plant is a tertiary-level treatment plant that meets all existing Title 22 treatment requirements. The Laguna Plant is currently permitted to treat 21.3 million gallons per day (mgd) average dry weather flow (ADWF); it treated approximately 15 mgd ADWF in 2010. Based on this, the Laguna Plant has adequate capacity to serve Project flows in addition to its existing commitments. The Project would not cause the Laguna Plant to exceed wastewater treatment requirements and would not require or result in the construction of new wastewater treatment facilities or expansion of existing facilities. No impact would occur to wastewater treatment facilities. The Project would connect to an existing commercial water account with the City of Santa Rosa. The estimated potable water demand (excluding irrigation) for the proposed Target store is 1.1 million gallons City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 79 GHD Inc. 12506-11-001 per year10. The City’s 2010 Urban Water Management Plan (UWMP) evaluates historical and projected water use and compares water supply to water demands projected through 2035 during normal, single‐dry, and multiple‐dry years (Santa Rosa 2011). As documented in the UWMP, Santa Rosa has sufficient water supplies to meet existing and projected demands through build-out of its General Plan, including under multiple dry-year scenarios. The Project would result in a net reduction in retail space compared to the area currently served under the existing commercial account. The water would be provided through existing entitlements and facilities and require no new or expanded water facilities. No impact would occur to potable water supply facilities. XVII. c) Require Construction or Expansion of New Storm Water Drainage Facilities – No Impact The Project would be designed in accordance with the City’s SUSMP Guidelines, which aim to address the impact of development on storm water runoff volume using low impact development (LID) measures integrated into the overall site design. On-site LID measures proposed for the Project include vegetated swales, bioretention basins, flowthrough planters, and storm drain inlet filters. The physical disturbance of these facilities during construction has been addressed in Section IX, Hydrology and Water Quality. The Project would not require or result in the construction of new off-site storm water drainage facilities or expansion of existing off-site facilities. No impact would occur. XVII. f, g) Have Sufficient Landfill Capacity and Comply with Statutes Related to Solid Waste – Less than Significant The City of Santa Rosa contracts with the North Bay Corporation to provide solid waste collection and recycling for commercial uses in Santa Rosa. The North Bay Corporation collects and transports commercial and residential solid waste to the Central Disposal Site Transfer Station at 500 Meacham Road north of Petaluma. Once at the transfer station, the solid waste is sorted and hauled to the following landfills: the Potrero Hills Landfill in Solano County (anticipated to be in operation until approximately 2030), the Redwood Sanitary Landfill in Marin County (anticipated to be in operation until approximately 2039), the Keller Canyon Landfill in Contra Costa County (anticipated to be in operation until approximately 2030) (Santa Rosa 2009b). During construction, there would be a temporary increase in solid waste disposal needs associated with construction wastes. Construction wastes for the Project would include solid waste from building demolition, as well as excess pavement, concrete, and soil associated with excavation and site grading. Both construction waste and operational solid waste could be accommodated by landfills located in the region. The impact from construction waste and commercial solid waste would be less than significant. 10 An irrigation demand has not been estimated, but includes efficient irrigation equipment and methods to comply with the Santa Rosa Water Efficient Landscape Ordinance.

Mandatory Findings of Significance Potentially Significant Impact Less-ThanSignificant With Mitigation Incorporation LessThanSignificant Impact No Impact Would the Project: a. Does the Project have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? b. Does the Project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a Project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)? c. Does the Project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? Discussion: XVII. a, c) Less than Significant with Mitigation With implementation of the mitigation measures presented herein, the Project does not have the potential to degrade the quality of the environment, including fish or wildlife species or their habitat, plant or animal communities, important examples of the major periods of California history or prehistory, or adverse effects on human beings. XVII. b) Less than Significant Cumulative impacts are defined as “two or more individual effects which, when considered together, are considerable or which compound or increase other environmental impacts” (CEQA Guidelines Section 15355). Cumulative impacts can result from individually minor, but collectively significant, actions taking place over a period of time. This IS/Proposed MND utilizes the “plan” approach, per CEQA Guidelines Section 15130(d), to determine if the Project makes a considerable contribution to a significant cumulative impact. Cumulative impacts have been identified using the summary of projections contained in the Santa Rosa General Plan 2035 Draft and Final EIR (Santa Rosa 2009b and 2009c). The General Plan 2035 Final EIR identified significant cumulative impacts related to transportation, air quality/climate change, and biological resources. Each of these cumulative impacts is summarized in more detail below. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 81 GHD Inc. 12506-11-001 Air Quality and Climate Change Impacts Significant unavoidable air quality and climate change impacts were identified in the General Plan Final EIR due to increased population and vehicle miles traveled (VMT) occurring at rates greater than assumed in regional air quality planning. The General Plan Final EIR identifies a significant unavoidable impact related to conflicts with implementation of the Bay Area Ozone Strategy, as well as with implementation of State or local goals for reducing greenhouse gas (GHG) emissions or generating GHG emissions that would exceed any applicable threshold of significance. As noted in this Initial Study’s air quality analysis (Section 3.III), the Project meets both the operational and construction screening criteria established by the BAAQMD and, therefore, would result in a less-than-significant cumulative impact to air quality from criteria air pollutant and precursor emissions. The General Plan Final EIR also identified a significant cumulative impact related to air toxics and objectionable odors. The cumulative impact was reduced to a less-than-significant level through mitigation requiring new sensitive uses located near high volume traffic routes to utilize air conditioning filtration systems. Such sensitive uses would include residences, schools, hospitals, and convalescent homes. The proposed Project does not meet this definition; therefore, it would not contribute to impacts identified in the General Plan Final EIR. The Project does not include any new sensitive uses or substantial increases in long-term traffic and, therefore, would not contribute to this cumulative impact. Biological Resources Impacts A significant biological resources impact was identified in the General Plan Final EIR related to conflicts with local, regional, or State habitat conservation plans for California tiger salamander. The Project site is not located in the area covered by the habitat plans adopted for the California tiger salamander. Therefore, the Project would not contribute to this cumulative impact. Transportation Impacts Significant unavoidable transportation impacts were identified in the General Plan Final EIR related to increased traffic volumes, delays, and decreases in levels-of-service (LOS) along U.S. Highway 101 and other city intersections. Such impacts which would be located in this Project area are LOSs on Guerneville Road, Steele Lane, and College/West College Avenue. The Traffic Impact Study conducted for this Project found that it would actually yield a net reduction in trips generated at Coddingtown Mall under the Future Cumulative Condition, compared to that of the General Plan buildout scenario (i.e., re-occupation of the Gottschalks building) due to the reduction in overall square footage. Therefore, the Project would have a beneficial contribution to future operation of the transportation network in the Project study area, as compared to that reported in the General Plan EIR; however, the 2035 Future Conditions may still exceed LOS standards as identified in the General Plan EIR. The Project’s contribution to this significant cumulative impact would not be cumulatively considerable, because the contribution would, in fact, be a net reduction compared to Future Cumulative Conditions. Therefore, the Project would not contribute to this cumulative impact. City of Santa Rosa Coddingtown Target Admin Draft IS/Proposed MND 82 GHD Inc. 12506-11-001 5.

The closest residences to the project site are located south of the project construction site, with additional residences farther south and to the east and west of the site (see Figure 1). A health risk assessment of the project construction activities was conducted that evaluated construction emissions of diesel particulate matter (DPM) and associated health risks to nearby residential areas. A dispersion model was used to predict the off-site concentrations resulting from project construction, so that lifetime cancer risks could be predicted. Construction period emissions were computed using the URBEMIS2007 model along with projected construction activity. Construction of the project is expected to occur over a fifteen month period during 2012 and 2013. Construction activities were assumed to occur 5 days per week between 8 am - 5 pm. The URBEMIS2007 model provided annual fine particulate matter (PM2.5) exhaust emissions (assumed to be DPM) for the off road construction equipment used for construction of the project of 0.035 and 0.030 tons per year for 2012 and 2013 construction years, respectively. On-road PM2.5 exhaust emissions were calculated by URBEMIS2007 as 0.0015 tons per year for 2012 and 2013. These on-road emissions are a result of on-road haul truck travel and vendor deliveries during construction. Since only the emissions that would occur at or near the project site would affect nearby local residences, it was assumed that 20 percent of the total on-road truck emissions would be associated with on-site activities or nearsite travel. The U.S. EPA ISCST3 dispersion model was used to predict concentrations of DPM at existing residences near the project site. The ISCST3 dispersion model is a BAAQMD recommended model for use in refined modeling analysis of CEQA projects 1. The ISCST3 modeling of construction activities used a single area source with a release height of 6 meters to represent the 1 BAAQMD. Recommended Methods for Screening and Modeling Local Risks and Hazards. Version 2.0, May 2011. Kristine Gaspar April 23, 2012 - Page 2 project construction area. Emissions were modeled as occurring between 8 am - 5 pm. Emissions for each of the construction years were modeled. The model used a 5-year data set (2001 – 2005) of hourly meteorological data from the Santa Rosa Airport, located about 3.2 miles southwest of the project site. Annual concentrations from construction activities were predicted for 2012 and 2013, with the concentrations for each construction year based on the 5-year average concentrations from modeling 5 years of meteorological data. Increased cancer risks were calculated using the maximum modeled annual concentration and BAAQMD recommended risk assessment methods for both a child exposure (3rd trimester through 2 years of age) and for an adult exposure. Since the modeling was conducted assuming emissions occurred 365 days per year, the default OEHHA2 exposure period of 350 days per year was used. Results of this assessment indicate a incremental child cancer risk of 2.4 excess cancer cases per million and the adult incremental cancer risk is 0.1 excess cancer cases per million. Under the BAAQMD CEQA Air Quality Guidelines, an incremental risk of greater than 10.0 cases per million from a single source at the Maximally Exposed Individual (MEI) would be a significant impact. The project’s cancer risks are well below the BAAQMD’s cancer risk threshold. Attachment A includes the emission calculations used for the area source modeling and the cancer risk calculations. Potential non-cancer health effects due to chronic exposure to DPM were also evaluated. The chronic inhalation reference exposure level (REL) for DPM is 5 micrograms per cubic meter (μg/m3). The maximum predicted annual DPM concentration from construction activities is 0.02 μg/m3, which is much lower than the REL. The Hazard Index (HI), which is the ratio of the annual DPM concentration to the REL, is 0.004. This HI is much lower than the BAAQMD significance criterion of a HI greater than 1.0. In addition to evaluating the health risks from DPM, potential impacts from PM2.5 emissions from the construction were evaluated. To evaluate potential non-cancer health effects due to PM2.5, the BAAQMD adopted a significance threshold of an annual average PM2.5concentration greater than 0.3 µg/m3. From the construction modeling for cancer risks, the maximum PM2.5 concentration was 0.02 μg/m3. This concentration is well below the BAAQMD PM2.5 threshold of greater than 0.3 µg/m3. Based on the above results, the project would have a less than significant impact with respect to community risk caused by construction activities. 2 OEHHA 2003.

The former Gottschalks store and several other out-facing commercial/office spaces on the south side of the shopping center would be demolished if the Target Store is approved. Because the shopping center was originally developed 50 years ago, the property has been evaluated for historical significance both for the purposes of the California Environmental Quality Act (CEQA) and at the request of the City of Santa Rosa. METHODOLOGY Interactive Resources prepared this historic resource evaluation by reviewing existing material provided by the Coddingtown Mall Property Management Office (including selected as-built drawings), undertaking archival research, and conducting a site visit to inspect the property and take photographs. The site visit was conducted on March 1, 2012. Archival research was undertaken at the Sonoma County History and Genealogy Library, the Santa Rosa Planning Department, the San Francisco Public Library website and various online resources. Additionally, a records search was carried out by the Northwest Information Center of the California Historical Resource Information System. The following report is intended to provide a historical evaluation of the property through a thorough analysis of the shopping center, its history and role in the development of Santa Rosa in order to determine if the property appears to be a historic resource as defined by the National Register of Historic Places, the California Register of Historic Resources, or the City of Santa Rosa.1 EVALUATION SUMMARY The National Register of Historic Places (NRHP) and the California Register of Historical Resources (CRHR) require that the resource be at least 50 years old (except under special circumstances), that it be significant under at least one of four criteria, and that it possess historic integrity. The four criteria include: association with historic events, association with important persons, distinctive design or physical characteristics, and the potential to provide important information about history or prehistory. In determining NRHP and CRHR eligibility, the author weighed known historical associations, architectural merit, and finally, the current level of Interactive Resources, Inc. Historic Resource Evaluation Page 1 March 27, 2012 Proposed Target Store at Coddingtown Mall integrity. Additionally, the City of Santa Rosa allows for the designation of landmarks if they are determined to have a specific historical, archaeological, cultural or architectural value in the City.2 After conducting the evaluation of the subject property, it appears that the shopping center, as a whole, is not eligible for listing on either the national or state registers, or as a local landmark. Although the property illustrates potentially locally significant associations with the development of northwest Santa Rosa, with a person significant in the development of Santa Rosa, Hugh Codding, and as a modest example of the Modern architectural style, the property does not appear to posses adequate significance for listing nor to maintain sufficient integrity to demonstrate these potential associations. Separately the revolving Coddingtown sign tower does appear to have local historical significance and is a listed Santa Rosa Landmark. SUMMARY HISTORY OF CODDINGTOWN MALL The history of Coddingtown Mall is most significantly tied to its namesake and developer, Hugh Codding. A property may be determined historically significant due to its association with the lives of persons significant in our past (Criteria 2/B). Therefore, the following background research has been completed on Hugh Codding, a person who appears to be potentially significant in the development of Santa Rosa. Codding was a central character in the postwar development of Santa Rosa and Sonoma County. Local journalist Gaye LeBaron wrote, “future historians may well consider him [Hugh Codding] a central figure in the second half of the county’s 20th century,” and that Codding’s developments “changed Santa Rosa more dramatically and more quickly than any change that had come before, with the possible exception of the ’06 quake.”3 Hugh Codding returned from the Navy in 1945 with $400 in discharge pay and constructed a house for speculation sale. He quickly moved on from individual homes to subdivisions to shopping centers. Town & Country Village was the first shopping center he constructed. With the profits from its sale, Codding purchased an orchard on Farmers Lane in east Santa Rosa and began the development of Montgomery Village. In addition to the shopping center, he constructed 2,600 houses in the area. Codding was proficient in self-promotion and gained national attention from Time magazine for various exploits such as building a house in less than four hours and a church in five hours and sixteen minutes. In 1955, through heated negotiations, Santa Rosa annexed Montgomery Village, and almost doubled the city’s population overnight.4 Codding’s business developments crashed in the mid-1950s, but had recovered by the end of the decade.5 He soon set his sights on the orchards northwest of Santa Rosa, near the newly completed U.S. Highway 101. Hugh and his wife, Nell, purchased land from the Indian Creek Lumber Company at Guerneville Road and Range Avenue, and aspired to create a new commercial development.6 In 1959, Codding had planned on naming the shopping center Interactive Resources, Inc. Historic Resource Evaluation Page 2 March 27, 2012 Proposed Target Store at Coddingtown Mall “Futureland.”7 As the project progressed, the development group officially incorporated as Santa Rosa Enterprises. The plans grew in scope and the development’s name was changed to Coddingtown. Further, the entire area west of the highway, and around the proposed shopping center, became known as the Coddingtown area. It eventually would include a professional park, housing subdivisions, an airport, a drive-in theater, and industrial enterprises.8 The various parcels were slowly annexed by Santa Rosa from Sonoma County over the course of two decades beginning in the early 1960s.9 The iconic, rotating Coddingtown sign tower is said to have been the first structure installed on the site between 1960 and 1962. One source states that the sign stood for two years in an undeveloped walnut orchard, before the new shopping center opened, which would infer that the tower was constructed in 1960; however a conflicting source would date the tower to 1962.10 The initial design for the sign included a 150-foot-tall structure resembling the Eiffel Tower, but this scheme was rejected by the Sonoma County Board of Zoning Adjustments.11 Instead the tower, which still stands and is a Santa Rosa Landmark, is much simpler with a revolving, neon name plate with “Codding” on one side and “Town” on the other. Welton Beckett and Associates, one of the foremost national firms specializing in the regional shopping center type, was hired to design the Coddingtown Regional Shopping Center. Headquartered in Los Angeles, the firm also had offices in San Francisco, New York, Houston, and Chicago.12 Welton Becket was well known not only for his Modern style, but also for his numerous commercial designs, including Stonestown (1950) in San Francisco, which may have been of particular significance to Codding. Drawings show that the firm continued to work on the completion of the center throughout the 1960s. Welton Becket died in 1969, yet the firm continued on through various iterations, and today is now part of AECOM.13 A property may also be found historically significant for its architectural design or as the work of a master (Criteria C/3). In the significance section below, the design of the shopping center is assessed for architectural significance within both its regional context and the within the context of the work of Welton Becket. Construction began on the shopping center in 1962. Thrifty Drug Company and Lucky Stores were the first companies to agree to locate in the new development, which would be touted as the largest regional shopping center between San Francisco and Portland.14 The first three buildings constructed (Buildings A, B, and C) were located in what would be the northwest section of the completed center. The Lucky Store – now a Whole Foods Market specialty store – and Thrifty Drug Company flanked ten other stores in between. Additionally, a Standard Oil station stood at the corner of Guerneville Road and Range Avenue; this structure no longer exists. Interactive Resources, Inc.

Interactive Resources, Inc. Historic Resource Evaluation Page 5 March 27, 2012 Proposed Target Store at Coddingtown Mall The following year, the last building at the north side (Building D) was constructed east of the existing three.15 Building D housed Roos Atkins, Smith’s and Joseph Magnin – now Sweet River Grill, Bank of the West, Village Sewing, Quizno’s Sub, Baskin Robbins, Pure Beauty, Great Clips and Fresh China. Codding continued work to expand the open air shopping center, and by the mid-1960s, both the Emporium and J.C. Penney agreed to come to Coddingtown. The twostory anchor stores were located south of the existing buildings, with J.C. Penney at the west and the Emporium at the east end. The Emporium – now a Macy’s Department Store – was constructed first and opened, along with two additional single-story commercial buildings to the west (Buildings F and G) in 1966. J.C. Penney was completed the following year. The facilities at Coddingtown remained essentially unchanged until 1979, when the company decided to enclose the shopping center and construct a building for a third anchor store. Liberty House opened in 1981 and was later occupied by Gottschalks Department Store. This structure was located on the south side of the shopping center, centered between the two other anchor department stores.16 In 2001, portions of Building C were demolished for the construction of an Old Navy Store. The most recent developments at Coddingtown include the demolition of Building A, the original Lucky store, and the construction of a new Whole Foods Market in its place; as well as, the redesign and construction of two entrances and of the northern facade of Building B.17 In addition to the shopping center itself, numerous parcels along the outer edge of the parking lot have been developed over the course of the past 50 years. The development includes: a post office, a branch library, commercial structures, and apartment buildings. While Coddingtown Mall thrived throughout its first several decades, it has lately seen a significant decline in its business. In 2009, the Gottschalks Department Store chain went out of business, leaving the Liberty House building vacant. The building has only been used sporadically since, primarily as temporary, holiday-centered commercial operations.

BRIEF DESCRIPTION OF CODDINGTOWN MALL Coddingtown Mall is situated in northwest Santa Rosa, directly west of U.S. Highway 101 along the south side of Guerneville Road. Standing on approximately 40 acres, the shopping center, Eshaped in plan, is surrounded by a large parking lot. Numerous small buildings line the outer edges of the parking area, mainly south of the shopping center, and a branch library stands at the north parking lot entrance at Guerneville Road. As explained above, the original shopping center was completed in 1967 with eight separate buildings connected by outdoor pedestrian promenades and plazas. Four single-story buildings were aligned on an east-west axis along the north side and two two-story anchor buildings, with two single-story buildings in between, were aligned on the same axis along the south side. In architectural style, the shopping center was Modern and functionally simple. The majority of the shopping center is single story, with flat roofs, and features a covered portico at most of the 1960s buildings. On the exterior, storefronts open directly out to the portico and the parking lots beyond. The simple stucco-clad elevations include wide, open bays defined by Interactive Resources, Inc. Historic Resource Evaluation Page 7 March 27, 2012 Proposed Target Store at Coddingtown Mall square columns and accented by recessed beams across the top of the openings. A high, stuccoclad parapet with a sheet metal cap completes the typical exterior elevations. The storefronts are set back under the protection of the portico and are all of varying designs consistent with each tenant company’s retail identity. Building D, the original Roos Atkins – now Sweet River Grill, Bank of the West and others-, follows the same general theme as the other single-story commercial buildings, with recessed store fronts and wide, open bays with square columns. The elevations are slightly unique in that the columns extend up to the canted parapet and are recessed within the rock embedded concrete cladding panels. The central bay on the north side has been updated with an arched glazed opening, stucco clad exterior and a stepped parapet. In 1980, the shopping center was enclosed and the last anchor store was constructed south of the existing buildings. The three anchor stores are all essentially two stories with flat roofs and are unified only in their use of tan-colored concrete masonry units at the exteriors. The eastern anchor store originally was designed for the Emporium and remains quite similar to its original appearance. Modern in style, the rectangular building is clad in tan split-faced concrete masonry units, and large vertical sections clad in ceramic tiles are employed to accent the entrances. The most notable exterior design feature is the two-story porch that extends off of the east side and is visible from U.S. Highway 101. Giant square columns extend up to the roof overhang and support a porch at the second floor. Period globe pendant lights hang from the porch ceiling, which features an incised geometric pattern. J.C. Penney was the second anchor store to be constructed at Coddingtown. Also Modern in style, the two-story rectangular box features an exposed white-painted, concrete frame with tan block infill cladding. At the ground floor, various structural bays are left open, revealing a portico surrounding the building, similar to those of the single-story commercial buildings. Historic photos show that originally there was no infill at the ground floor bays. Finally, a simple rectangular eave projects out from the building’s parapet. The third anchor store – the former Liberty House and Gottschalks structure – is a stylistic departure from the original shopping center.20 The rectangular two-story building with a flat roof, features a stucco-clad second story that slightly cantilevers out over the split-face tan blockclad first story. At the building’s three exterior entrances, a large glass box extends out over the recessed doorways. Also in 1980, the exterior pedestrian promenades throughout the shopping center were enclosed with rows of clerestory windows, exposed deep wood beams and wood ceilings. Old Navy came to the shopping center in 2001. Codding Construction, working with architect Starrett of Santa Rosa, demolished a portion of Building C and built a new store. In 2010, a Whole Foods Market went in at the site of the original Lucky grocery store (Building A.)21 The original building demolished was replaced with a new structure designed by Wix Architecture of Interactive Resources, Inc. Historic Resource Evaluation Page 8 March 27, 2012 Proposed Target Store at Coddingtown Mall Santa Rosa.22 Two new modern entrances, design by ELS Architecture of Berkeley, of metal, wood panels, frosted glass and slate were constructed in the past year on the north side of Macy’s (Building E) and between Buildings B and C.23 Additionally, the north façade of Building C (Old Navy) is currently under renovations. The existing Building C commercial space has been redesigned by ELS Architecture to accommodate a new BJ’s restaurant.24 EVALUATION CRITERIA National Register of Historic Places National Register Bulletin Number 15, How to Apply the National Register Criteria for Evaluation, describes the Criteria for Evaluation as being composed of two factors. First, the property must be “associated with an important historic context.”25 The National Register identifies four possible context types, of which at least one must be applicable at the national, state, or local level. As listed under Section 8, “Statement of Significance,” of the National Register of Historic Places Registration Form, these are: “A. Property is associated with events that have made a significant contribution to the broad patterns of our history. “B. Property is associated with the lives of persons significant in our past. “C. Property embodies the distinctive characteristics of a type, period, or method of construction or represents the work of a master, or possesses high artistic values, or represents a significant and distinguishable entity whose components lack individual distinction. “D. Property has yielded, or is likely to yield, information important to prehistory or history.”26 Second, for a property to qualify under the National Register’s Criteria for Evaluation, it must also retain “historic integrity of those features necessary to convey its significance.”27 While a property’s significance relates to its role within a specific historic context, its integrity refers to “a property’s physical features and how they relate to its significance.”28 To determine if a property retains the physical characteristics corresponding to its historic context, the National Register has identified seven aspects of integrity. These are: “Location is the place where the historic property was constructed or the place where the historic event occurred... “Design is the combination of elements that create the form, plan, space, Interactive Resources, Inc. Historic Resource Evaluation Page 9 March 27, 2012 Proposed Target Store at Coddingtown Mall structure, and style of a property... “Setting is the physical environment of a historic property... “Materials is the physical elements that were combined or deposited during a particular period of time and in a particular pattern or configuration to form a historic property... “Workmanship is the physical evidence of the crafts of a particular culture or people during any given period in history or prehistory... “Feeling is a property’s expression of the aesthetic or historic sense of a particular period of time... “Association is the direct link between an important historic event or person and a historic property.”29 Since integrity is based on a property’s significance within a specific historic context, an evaluation of a property’s integrity can only occur after historic significance has been established.30 California Register of Historical Resources California Office of Historic Preservation’s Technical Assistance Series #6, California Register and National Register: a Comparison, outlines the differences between the federal and state processes. The context types to be used when establishing the significance of a property for listing on the California Register are very similar, with emphasis on local and state significance. They are: “1. It is associated with events that have made a significant contribution to the broad patterns of local or regional history, or the cultural heritage of California or the United States; or “2. It is associated with the lives of persons important to local, California, or national history; or “3. It embodies the distinctive characteristics of a type, period, region, or method of construction or represents the work of a master, or possesses high artistic values; or “4. It has yielded, or is likely to yield, information important to prehistory or Interactive Resources, Inc. Historic Resource Evaluation Page 10 March 27, 2012 Proposed Target Store at Coddingtown Mall history of the local area, California, or the nation.”31 A property must also retain sufficient integrity based on the seven aspects previously identified. A property may not maintain sufficient integrity for listing on the NRHP, but may still be eligible for listing in the CRHR if it maintain the potential to yield significant scientific or historical information or specific data.32 City of Santa Rosa Recognizing the value of Santa Rosa's historic resources, the City Council adopted a Preservation Ordinance in 1988 and created the City's Cultural Heritage Board. Santa Rosa's ongoing support of preservation planning is also expressed in the City's General Plan which includes Element 11, Historic Preservation, in the City of Santa Rosa’s 2035 General Plan. Further, Article III of Chapter 17-22 of the City Code allows for the City Council to designate landmarks and defines a landmark as “any site… place, building, structure, street, street furniture, sign, work of art, natural feature or other object having a specific historical, archaeological, cultural or architectural value in the City.” Coddingtown Mall, or any portion thereof, is not currently listed on either the National or State registers. However, the freestanding Coddingtown Revolving Sign Tower was designated as a local Santa Rosa Landmark in 1993. The Cultural Heritage Board initially denied the application, however the Santa Rosa City Council agreed with the applicant and found the sign eligible for landmark status.33 EVALUATION OF SIGNIFICANCE Age This first consideration for determining a property’s eligibility is age. Typically a building must be at least 50 years old, unless special circumstances exist. The revolving sign was installed at the site circa 1960 and the first structures of the shopping center were constructed in 1962. The original vision of an outdoor regional shopping center was completed in 1967, with the construction of the second anchor story, J.C. Penney. The buildings of the 1960s original shopping center range in age from 45 to 50 years old. A property under 50 years old may be listed on the NRHP only if it is “of exceptional importance,” however the CRHR is less stringent stating that a property may be considered “if it can be demonstrated that sufficient time has passed to understand [their] historical importance.”34 Therefore, due to the age and the potential for special criteria considerations, the property is eligible for review. The Gottschalks building was constructed in 1980 and is only 32 years old. As a result of the research conducted for this report, no evidence has emerged that this building is of exceptional Interactive Resources, Inc. Historic Resource Evaluation Page 11 March 27, 2012 Proposed Target Store at Coddingtown Mall importance or of any historical importance. It appears simply to be a typical commercial shopping center structure of its period and does not maintain any historical significance. Criterion A (NRHP)/ Criterion 1(CRHR): The Coddingtown Regional Shopping Center was part of a the mass decentralization of urban centers that occurred throughout the 1950s and 1960s in the United States. In Santa Rosa, the shopping center was part of the larger overall development of the area northwest of the downtown. Spearheaded by Hugh Codding, the area eventually featured not only commercial development, but also residential subdivisions, an industrial park, professional offices, theaters, and even an airport. The examples of decentralization are numerous throughout the nation and the state, but the role the shopping center played as a catalyst for the development of the Coddingtown area may be significant at a local level. It does not appear that the property would be significant under Criteria A/1, because its associations with events of the broad patterns of our history, i.e., the decentralization of the urban downtown, are not particularly unique to the nation or the state, but the property may have some significance locally in relation to the development of northwest Santa Rosa. Criterion B(NRHP)/Criterion 2(CRHR): Hugh Codding was a larger-than-life character in the history of Santa Rosa. As arguably the most significant local developer in the second half of the twentieth century, he had significant influence on the growth of postwar Santa Rosa. As evidenced by the sign, Coddingtown was Codding’s project from the start, and Codding Enterprises remains partial owner of the shopping center today. It appears the property may have some significance under Criteria B/2 at the local level only for its association with Hugh Codding, a significant person in the history of Santa Rosa.35 Criterion C(NRHP)/Criterion 3(CRHR): The structures constructed in the 1960s were designed by the firm Welton Becket and Associates out of their San Francisco office. Welton Becket was a large national firm that designed a significant number of commercial properties. Notably, Stonestown Mall in San Francisco, constructed in 1950, was an early regional shopping center designed by the firm. The design of Coddingtown was never realized as it had initially be rendered in 1962, yet many of the overall characteristics appeared, such as the general configuration of the buildings and the colonnaded portico that surrounded most structures. The influence of Welton Becket is visible today in the two anchor stores at the east and west ends, which also still embody the Modern architectural style popular in mid-century commercial architecture. However, Coddingtown is not a notable design of Becket or the firm. Some of his renowned projects include the Kaiser Center in Oakland, the Capitol Records Building in Hollywood, and the Los Angeles Music Center. Further, the revolving sign tower (design unknown) is illustrative of the period and is a modest example of the Googie style. Googie as an architectural style within Modernism developed through commercial vernacular architecture, centered in Los Angeles, in the early 1950s.The style is characterized by bright colors, rakish diagonal, and bold signs.36 Interactive Resources, Inc. Historic Resource Evaluation Page 12 March 27, 2012 Proposed Target Store at Coddingtown Mall It appears that only Buildings G and H, the anchor department stores, may meet the criteria for eligibility under Criterion 3/1, however these buildings are only modest examples of Modern commercial architecture and of the work of Welton Becket. Additionally, the tower sign appears potentially eligible for listing as a local example of a modest Googie design. Criterion D (NRHP)/ Criterion 4(CRHR): This criterion is associated with archeology and, at this time, it does not appear that the subject property has yielded, or is likely to yield, information important to prehistory or history of the local area, California, or the nation. Significance Summary After an initial evaluation of the shopping center, it appears that the property may have minor significance under Criterion A/1 for its association with the development of northwest Santa Rosa, under Criterion B/2 for its association with Hugh Codding, and under Criterion C/3 as the work of Welton Becket completed in the Modern style. Independently, the sign tower appears to maintain local significance for its association with Hugh Codding and for its Googie style. Overall, the historic significance of the property under any of the three criteria appears to be minor and only potentially significant at the local level. Further, as much of the property is less than 50 years old and does not appear to be of exceptional importance, the property would not be eligible for listing on the NRHP Because the threshold is lower, the property may have some significance at the state level, therefore the level of integrity is assessed below. Integrity After the historic significance has been established, a property’s integrity must also be assessed. For a property to qualify as historically significant under either the NRHP or the CRHR, it must retain historic integrity of those features necessary to convey its significance.37 While a property’s significance relates to its role within a specific historic context, its integrity refers to “a property’s physical features and how they relate to its significance.”38 Further, for a building to meet registration requirements under Criterion C/3 (Architecture) as an individual resource, the property would need to retain sufficient character-defining features in order to reflect design intent. To determine if a property retains the physical characteristics corresponding to its historic context, the NRHP and the CRHR have identified seven aspects of integrity (explained above), as follows: 1. Location The property remains at its original site and retains the integrity of location. 2. Design The original design of the shopping center has been significantly altered. The original Lucky’s building has been demolished and portions of the Thrity were also partially demolished. Both were replaced with new structures. The outdoor pedestrian promenades were enclosed and a new Interactive Resources, Inc. Historic Resource Evaluation Page 13 March 27, 2012 Proposed Target Store at Coddingtown Mall two-story anchor department store constructed. New entrances have been constructed at two locations and facades are currently being renovated. The single-story commercial buildings retain some of the original design elements, namely the colonnaded portico, but it appears that the exterior wall cladding has been altered on several buildings and features, such as projecting eaves have been removed. . The only two buildings that appear to retain their integrity of design are the two anchor department stores at the east and west ends of the shopping center (J.C. Penney and Macy’s). Overall, the shopping center does not retain its integrity of design. 3. Setting The overall setting remains essentially the same as at the time of the original construction. The shopping center is surrounded by a large parking area, is adjacent to U.S. highway 101, and there is development at the outskirts of the property. Although, there are no longer any orchards nearby, the property itself essentially retains its integrity of setting. 4. Materials Only the two anchor stores retain the integrity of their materials. The majority of the single-story commercial buildings have been so significantly altered , that they no longer maintain their integrity of material. 5. Workmanship The only workmanship evident is in the two anchor stores, as the outward expression of the technology of the period, i.e. the exposed structure, it still evident. The remaining structures have been so extensively altered that the overall property no longer maintains its integrity of workmanship. 6. Feeling The extensive alterations have greatly altered the feeling of the overall property. Only portions of the shopping center, namely the J.C. Penney and Macy’s buildings, clearly express the Modern aesthetic. Because the property no longer maintains its expression of its period as a whole, it does not retain the integrity of feeling. 7. Association The property maintains its associations with Hugh Codding and with the historical development of northwest Santa Rosa, primarily through the revolving sign tower and the recognition of the general neighborhood as Coddingtown. Overall, the property does not retain sufficient integrity to convey its significance. Only three pieces of the overall property possess integrity: the two anchor department stores and the revolving tower sign. The shopping center was developed as a whole composed of eight buildings. Because six of the buildings have been extensively altered and additions have been constructed, the property is no longer able to convey it original design intent and expression. Interactive Resources, Inc. Historic Resource Evaluation Page 14 March 27, 2012 Proposed Target Store at Coddingtown Mall SUMMARY OF FINDINGS At the request of GHD Inc., a historic resource evaluation has been conducted on the subject property prior to the demolition of the former Liberty House/Gottschalks building and the development of a new Target store. Coddingtown Mall is not currently listed on either the national or state register, however the revolving tower sign in the parking lot is a designated as a Santa Rosa Landmark. After a physical evaluation of the property and an examination of related archival material, it appears that the shopping center as a whole would be ineligible for the National Register of Historic Places due to portions of the property’s age (i.e., under 50 years) and general lack of significance. This evaluation also indicates that the shopping center is ineligible for the California Register of Historic Resources and designation as a Santa Rosa Landmark due to its lack of integrity. Only the revolving Coddingtown tower sign, a listed Santa Rosa Landmark, appears to maintain any historical significance. .39 For the purposes of the California Environmental Qualities Act, the buildings at Coddingtown Mall would not be considered historic resources as defined by Section 15064.5. The Coddingtown tower sign is the only historic resource within the vicinity of the project and it does not appear the sign would be impacted by the proposed work.. Therefore, the proposed project would not have a significant impact on any historic resources.

Shared Parking Summary Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page i Executive Summary The proposed project includes the demolition of the anchor store space most recently occupied by Gottschalks as well as some small stores along the perimeter of the Coddingtown Mall in the City of Santa Rosa. The 201,631 square feet of store space being demolished will be replaced with a 143,487 square foot Target store. The trip generation for the Coddingtown Mall as a whole is expected to decrease by 1,327 trips on average during a weekday, including 171 fewer trips during the p.m. peak hour. Likewise, the site’s trip generation will decrease by 2,078 trips on average on a Saturday, including 242 fewer trips during the midday peak hour. The study area was established to include intersections where both streets are either Regional/Arterial Streets or Transitional/Collector Streets. The analysis indicates that all of the 13 study intersections are currently operating acceptably, with average delays indicating LOS D operation or better, and acceptable operation is expected to continue with project-generated traffic added. It should be noted that because the anchor tenant space was mostly unoccupied, so not generating trips, when the traffic counts were taken, there is a net increase in trips due to the project compared to existing conditions. The analysis reflects 138 added new p.m. peak hour trips and an increase of 156 new trips during the weekend peak hour once deductions for pass-by (trips already on Guerneville Road, Range Avenue or Cleveland Avenue) and diverted link trips (trips already on US 101) are taken. Because the project results in fewer trips than would be generated by re-occupation of the existing anchor tenant space, the project has a net beneficial impact on future traffic operation compared to what has been evaluated based on projections that include the existing shopping center space. The potential impact in light of the North Santa Rosa Station Area Plan was also evaluated, and the change in use is again expected to have a net beneficial impact compared with re-occupation of the existing, but currently vacant, anchor store space. The study intersections of Guerneville Road/Range Avenue and Steele Lane/US 101 North Ramps experienced collisions at a rate higher than the statewide average for intersections with similar configurations and controls. The intersection of Guerneville Road/Range Avenue has recently been upgraded to reduce pedestrian crossing time, which improves conditions at this location. The recent US 101 Widening project added capacity that can be expected to reduce the congestion-related types of crashes that occur at this location. The study area has a well-connected system of existing and planned facilities for pedestrians and bicyclists. Transit users are well served at the project site by the Northside Transit Transfer Center located at the Coddingtown Mall. Site access will remain unchanged with the project. Some minor modifications in terms of the orientation of parking fields in the area to the south of the store are expected to improve circulation. The parking supply of 3,323 spaces proposed does not meet the parking requirements under the City’s Code of 3,424 parking spaces, but analysis of shared parking indicates that a supply of 3,183 parking spaces is sufficient. It is recommended that the City accept the shared parking analysis and proposed parking supply through approval of the Conditional Use Permit. Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 1 Introduction Introduction This report presents an analysis of the potential traffic impacts that would be associated with development of a proposed Target Store to be located at the Coddingtown Mall in the City of Santa Rosa. The traffic study was completed in accordance with the criteria established by the City of Santa Rosa, and is consistent with standard traffic engineering techniques. Prelude The purpose of a traffic impact study is to provide City staff and policy makers with data that they can use to make an informed decision regarding the potential traffic impacts of a proposed project, and any associated improvements that would be required in order to mitigate these impacts to a less-thansignificant level as defined by the City’s General Plan or other policies. Vehicular traffic impacts are typically evaluated by determining the number of new trips that the proposed use would be expected to generate, distributing these trips to the surrounding street system based on existing travel patterns or anticipated travel patterns specific to the proposed project, then analyzing the impact the new traffic would be expected to have on critical intersections or roadway segments. Impacts relative to safety, including for pedestrians and bicyclists, and to transit are also addressed. Project Profile The proposed Target Store is intended to be developed within areas currently occupied by the space that most recently housed Gottschalks as well as a portion of the parking lot and some small stores along the perimeter of the Coddingtown Mall in the City of Santa Rosa. The project includes a 143,487 square foot Target store. As part of the project, 46,754 square feet of space currently occupied by small shops as well as the 154,877 anchor building will be demolished. The project site is located within the Coddingtown Mall, as shown in Figure 1.

Guerneville Road/Range Avenue Guerneville Road/West Steele Lane-Coddingtown Driveway Guerneville Road/Cleveland Avenue Steele Lane/US 101 South Steele Lane/US 101 North Steele Lane/Illinois Avenue-County Center Drive Coddingtown Driveway/Cleveland Avenue Jennings Avenue/Range Avenue Jennings Avenue/Cleveland Avenue Frances Street/Cleveland Avenue College Avenue/Cleveland Avenue College Avenue/US 101 South College Avenue/US 101 North In establishing the study area, intersections of streets identified in the Santa Rosa General Plan 2035 as either Regional/Arterial Streets (such as Guerneville Road) or Transitional/Collector Streets (such as Jennings Avenue) were included. Consideration was given to evaluating the intersections of Edwards Avenue at both Range Avenue and Cleveland Avenue since a minimal amount of project traffic could use this roadway, but a review of operation based on count data from 2008 for the evening peak hour indicated that these two intersections at either end of the block are currently operating at LOS B or C, well above the minimum threshold of LOS D. Further, a sensitivity analysis indicates that volumes would need to increase by at least 50 percent on all movements for operation to deteriorate to unacceptable levels. Since this preliminary assessment indicated that no improvements would be necessary, it was determined that these two minor intersections did not warrant further study. Operating conditions during the weekday p.m. and weekend midday peak periods were evaluated as these time periods reflect the highest traffic volumes areawide and for the proposed project. The evening peak hour occurs between 4:00 and 6:00 p.m. and typically reflects the highest level of congestion of the day during the homeward bound commute, while the weekend midday peak occurs between 12:00 and 2:00 p.m. Study Intersections Guerneville Road/Range Avenue is a signalized, four-legged intersection with protected left-turn movements on the east-west Guerneville Road approaches and split, or exclusive, phasing on the northsouth Range Avenue movements.

The posted speed limit is 40 miles per hour (mph) west of Range Avenue and decreases to 35 mph east of Range Avenue. This road is classified in the Santa Rosa General Plan as a regional/arterial street. Sidewalks are provided on both sides of the street. Class II bicycle lanes are provided along both sides of the street west of West Steele Lane-Coddingtown Driveway. Range Avenue-Frances Street north of Guerneville Road is a four-lane north-south street with left-turn lanes at intersections. Along the frontage of Coddingtown Mall the corridor has five lanes (two lanes in each direction and a center two-way left-turn lane) that transition to a two-lane street south of the mall. A two-way left turn lane is present south of Jennings Avenue for approximately 900 feet where the street turns into Frances Street and transitions back to a two-lane roadway. North of Guerneville Road the posted speed limit is 40 mph, and to the south it is 30 mph. The Santa Rosa General Plan classifies this road as a transitional/collector street. Sidewalks are provided on both sides of the street north of Edwards Avenue, but south of this street they are intermittent. Bicycle lanes are provided on Range Avenue north of Steele Lane, and a southbound bicycle lane is provided along a recent residential development south of Jennings Avenue. Cleveland Avenue has four north-south lanes, with two lanes southbound, one lane northbound and a center two-way left-turn lane. However; adjacent to Coddingtown Mall, the street widens to two lanes in each direction plus a center two-way left-turn lane which continues to the north. The posted speed limit is 35 mph. This segment is classified as a regional/arterial street. Continuous sidewalks are provided along both sides of the street to the north of Guerneville Road. To the south of Guerneville Road, sidewalks exist along the west side of the street, but most of the east side of the street abuts the freeway and therefore has no sidewalks (and no pedestrian demand). Sidewalks do exist on the east side of the street near Coddingtown Mall and south of Ridgway Avenue where Cleveland Avenue is further away from the freeway. Collision History The collision histories for the study intersections were reviewed to determine any trends or patterns that may indicate a safety issue. Collision rates were calculated based on records available from the California Highway Patrol as published in their Statewide Integrated Traffic Records System (SWITRS) reports. The study covered the most current three-year period available, which is January 1, 2008, through December 31, 2010. The calculated collision rates for the study intersections were compared to average collision rates for similar facilities statewide, as indicated in 2007 Collision Data on California State Highways, California Department of Transportation. With the exception of Guerneville Road at Range Avenue and Steele Lane at US 101 North, all of the study intersections were determined to have experienced collisions at a lower rate than the statewide average for similar facilities (four-way signalized intersection, stopcontrolled tee intersection, etc.). The collision records for Guerneville Road and Range Avenue were further reviewed for any indication of a specific concern as indicated by a high incidence of one type of crash. However, with five different primary collision factors among the 19 collisions and seven different approach direction combinations, no particular pattern is apparent. Of most concern is a fatal pedestrian crash that occurred in 2009 and a bicycle-involved crash four months later. Both of these crashes involved westbound through vehicles and pedestrians or cyclists crossing Guerneville Road, though from the available data fault cannot be determined nor can it be ascertained if they were on the east or west side of the intersection. The Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 7 fatality occurred around sunset, which may have contributed. The City completed a project during the summer of 2011 that reduced the length of the crossing on the east leg, and this project would be expected to have a positive impact on pedestrian safety. It should be noted that the collision records for the Steele Lane interchange do not differentiate between the northbound and southbound ramps, so crashes involving only vehicles on Steele Lane (eastbound and westbound) were assigned to one or the other ramp intersection based on the direction and type of crash. There were six crashes assigned to the northbound ramp intersection that could have occurred at the southbound ramp intersection, and the rates for these two intersections together averages out to be almost equal to the statewide average. However, since the rate developed for the northbound ramp was higher than the applicable statewide average, the crash records were reviewed in greater detail. It was noted that of the 25 collisions assigned to the intersection, there were six primary factors, though by far the greatest incidence was rear-ends (eleven crashes) followed by broadside and sideswipe (five each). Directionally, the most predominant combination was two northbound vehicles (ten collisions). This type of collision history is common at intersections that experience congestion or where there are multiple lanes and drivers make sudden lane changes. With only five collisions in the last year of the study period, it appears that the capacity enhancements (added lanes as part of the US 101 widening project) and signal timing improvements (implementation of adaptive signal timing) have improved operation and safety. Finally, it should be noted that there was a pedestrian-involved crash at this location as well, though it resulted in injuries and not a fatality. The results of the collision rate analysis are presented in Table 1 and copies of the calculation sheets are provided in Appendix A.

Obstacles to bicycle movement in the study area include the Sonoma-Marin Area Rail Transit (SMART) track and US 101, both of which run in a generally north-south direction and limit east-west access between residential neighborhoods and major community destinations. East-west access across the SMART rail corridor is provided at three atgrade crossings within the study area along the following streets: West Steele Lane, Guerneville Road, and College Avenue. East-west access across the US 101 corridor is provided via highway undercrossings at Steele Lane and College Avenue. The Santa Rosa Bicycle and Pedestrian Master Plan classifies bikeways into three categories: • • • Class I Bike Path: a completely separated right of way for the exclusive use of bicycles and pedestrians with cross-flow minimized. Class II Bike Lane: a striped lane for one-way bike travel on a street or highway. Class III Bike Route: shared use with pedestrian or motor vehicle traffic. Existing and planned bikeways in the Study Area, as contained in the 2010 Santa Rosa Bicycle and Pedestrian Master Plan, are summarized in Table 2.

Significant portions of the City’s on-street bikeway network within the study area are completed, and although the existing bikeway network is not completely contiguous, bicyclists traveling to the site from outlying neighborhoods can choose from a variety of on- and off-street bikeways that lead towards the site. In the immediate vicinity of the Shopping Center, direct access is provided to the site for bicyclists from the west via Class II bike lanes on Guerneville Road west of West Steele Lane. Planned bikeway improvements in the study area can be found in a variety of City documents including the Santa Rosa General Plan, the Santa Rosa Bicycle and Pedestrian Master Plan, the Citywide Creek Master Plan, and the Capital Improvement Program. A Class I SMART multi-use pathway planned in the study area would improve access to the site. The SMART pathway is a proposed regional Class I bikeway that will provide a continuous nonmotorized transportation route within or adjacent to the SMART railroad right-of-way. The SMART Path has been planned as the primary north-south route in the City and County’s primary bikeway networks, and the overall project is a focal point in local and regional bikeway, land-use, and transportation plans. Implementation of the SMART Path has begun in Santa Rosa. The first phase of the project is funded for construction and will extend from 8th Street, adjacent to the Downtown SMART Station, north to College Avenue. The second phase, which is currently unfunded, will extend from College Avenue north to Jennings Avenue. The limits of Phase III, also unfunded, include the Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 10 segment extending from Jennings Avenue north to Guerneville Road near the project site. Completion of the pathway will allow bicyclists and pedestrians to travel to the project site via primarily a dedicated north-south multi-use pathway that is completely separate from the surrounding roadway network. Pedestrian Pedestrian facilities include sidewalks, crosswalks, pedestrian signals, curb ramps, and streetscape amenities. Nearly complete sidewalk coverage, accessible curb ramps, and marked crosswalks are provided along arterial streets in the study area. Sidewalks in the study area generally range in width from four to ten feet. Pedestrian amenities provided throughout the study area include accessible pedestrian ramps, pedestrian signals and crosswalk treatments. While the pedestrian network is generally well-developed in the study area, there are some locations where gaps in the sidewalk network can be found. Short gaps exist along undeveloped properties and various frontages on College Avenue, Jennings Avenue, and Guerneville Road. To address east-west access across US 101 in the Junior College and North Station Area, a bicycle and pedestrian bridge over US 101 has been proposed. In 2008/09, the City conducted a feasibility study to evaluate the need for a bicycle and pedestrian bridge in the area, and to identify potential alignments for a bridge and its associated ramp structures. The study identified a preferred alignment that would connect Elliot Avenue on the east side of US 101 to Coddingtown on west side, adjacent and through the project site. Additional Caltrans studies are required to advance the project further, and while the City has authorized additional work to provide environmental clearance documentation for the project, due to costs and changing community priorities, a timeframe for project implementation is unknown at this time. Capital Improvement Program (CIP) Bicycle and Pedestrian Improvements Santa Rosa’s 2011/12 Capital improvement Plan (CIP), Bicycle and Pedestrian Master Plan and Citywide Creek Master Plan include the following projects and/or programs affecting pedestrian and bicycle circulation within the study area. • • • • SMART Path Phase 3 Jennings Avenue to Guerneville Road (currently unfunded, included in the Bicycle and Pedestrian Master Plan) – Constructs a portion of the SMART multi-user path along the rail corridor Jennings Avenue Rail Crossing (funding included in 2011/12 CIP) – Pedestrian and bicycle crossing of the SMART rail tracks Highway 101 Bike/Pedestrian Overcrossing (currently unfunded. Priority #1 in the Bicycle and Pedestrian Master Plan) – Pedestrian and bicycle overpass linking the SRJC area with the Coddingtown Mall area Improve Transit and Shuttle Service on the east side of Range Avenue at Coddingtown Mall to include off-street stops and a bus turnaround area (funding from redevelopment included in 2011/12 CIP) Transit Santa Rosa CityBus Santa Rosa CityBus is the primary transit provider in Santa Rosa. CityBus provides regularly-scheduled fixed-route service to residential neighborhoods, major activity centers, and transit hubs within the City limits. Seventeen fixed routes are operated with wheelchair accessible, low-floor buses which can accommodate up to two bikes on bike racks attached to the front of each bus. CityBus routes are Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 11 designed around a timed-transfer method where buses serving different routes arrive and depart at designated transfer locations at routine periodic intervals. On weekdays, routes typically depart every 30 minutes between 6:00 a.m. and 7:45 p.m. On Saturdays, routes depart every hour between 6:00 a.m. and 7:00 p.m. (routes 9 and 12 depart every 30 minutes). On Sundays, routes typically depart every hour between 10:00 a.m. and 4:45 p.m. The primary transit hub in the study area is the Northside Transit Transfer Center which is located on the westerly side of the Coddingtown Mall. The Northside Transit Transfer Center consists of an extended bus pullout with a series of all-weather transit shelters, benches, street lighting, bicycle parking, and an information kiosk. The site serves CityBus routes 10, 11, 15, and 17. Paratransit Paratransit, also known as dial-a-ride or door-to-door service, is available for those who are unable to independently use the transit system due to a physical or mental disability. Individuals must be registered and certified as ADA eligible before using the service. The City currently contracts out paratransit service which provides curb-to-curb transportation for disabled riders within city limits and in the Roseland area. Service hours are Monday through Saturday from 6:00 a.m. to 8:00 p.m. and Sunday from 9:00 a.m. to 5:00 p.m. Ride reservations can be scheduled daily. Sonoma County Transit Sonoma County Transit also provides regular service into and around the City of Santa Rosa and the study area. Sonoma County Transit Routes 44 and 48 serve the Northside Transit Transfer Center and run on a one to two hour headway schedule on weekdays and two to three hour headway schedule on weekends. SMART Rail Transit The SMART commuter rail system is a 70-mile rail line that is planned to run from Cloverdale, at the north end of Sonoma County, to Larkspur, where the Golden Gate Ferry connects Marin County with San Francisco. Along the way, SMART will have stations at the major population and job centers of the North Bay including the Guerneville Road station. At buildout, SMART will also provide a critical northsouth transportation route for bicyclists and pedestrians, with a combination of multi-use pathways and on-street facilities located along or adjacent to the right-of-way between Cloverdale and Larkspur. The 14 stations along the corridor are being designed to accommodate available feeder bus services, shuttle services and, in selected suburban locations, park and ride facilities. Commuter-oriented passenger train service will be provided by an estimated 14 round-trip trains per day operating at 30-minute intervals in the morning and evening peak commute hours during the week. SMART is planning to initiate rail service in the year 2015 or 2016 on what is being referred to as the initial operating segment (IOS). The IOS runs from downtown Santa Rosa on the north to the San Rafael Civic Center on the south. It is unknown at this time when service would commence at the North Santa Rosa station, though the station remains part of the SMART operating plan and financing. The North Santa Rosa SMART station will be located on the south side of Guerneville Road and east side of the SMART tracks. It will include a raised platform with shelter, benches, and ticket kiosks between the mainline tracks and a rail siding. Access to the platform will be via Guerneville Road on the north and a new prefabricated pedestrian/bicycle bridge over a drainage channel on the south. The station will include a transit plaza for bus transfers as well as bicycle racks. The station will also include 350 commuter parking spaces. Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 12 Capacity Analysis Intersection Level of Service Methodologies Level of Service (LOS) is used to rank traffic operation on various types of facilities based on traffic volumes and roadway capacity using a series of letter designations ranging from A to F. Generally, Level of Service A represents free flow conditions and Level of Service F represents forced flow or breakdown conditions. A unit of measure that indicates a level of delay generally accompanies the LOS designation. The study intersections were analyzed for short-term conditions using methodologies published in the Highway Capacity Manual (HCM), Transportation Research Board, 2000. This source contains methodologies for various types of intersection control, all of which are related to a measurement of delay in average number of seconds per vehicle. The Levels of Service for the intersections with side street stop controls, or those which are unsignalized and have one or two approaches stop controlled, were analyzed using the “Two-Way StopControlled” intersection capacity method from the HCM. This methodology determines a level of service for each minor turning movement by estimating the level of average delay in seconds per vehicle. Results are presented for individual movements together with the weighted overall age delay for the intersection. The study intersections with stop signs on all approaches were analyzed using the “All-Way StopControlled” intersection methodology from the HCM. This methodology evaluates delay for each approach based on turning movements, opposing and conflicting traffic volumes, and the number of lanes. Average vehicle delay is computed for the intersection as a whole, and is then related to a Level of Service. The study intersections that are currently controlled by a traffic signal were evaluated using the signalized methodology from the HCM. This methodology is based on factors including traffic volumes, green time for each movement, phasing, whether or not the signals are coordinated, truck traffic, and pedestrian activity. Average stopped delay per vehicle in seconds is used as the basis for evaluation in this LOS methodology. For purposes of this study, delays were calculated using optimized signal timing. The ranges of delay associated with the various levels of service are indicated in Table 3. Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 13 Table 3 Intersection Level of Service Criteria LOS Two-Way Stop-Controlled All-Way Stop-Controlled Signalized A Delay of 0 to 10 seconds. Gaps in traffic are readily available for drivers exiting the minor street. Delay of 0 to 10 seconds. Upon stopping, drivers are immediately able to proceed. Delay of 0 to 10 seconds. Most vehicles arrive during the green phase, so do not stop at all. B Delay of 10 to 15 seconds. Gaps in traffic are somewhat less readily available than with LOS A, but no queuing occurs on the minor street. Delay of 10 to 15 seconds. Drivers may wait for one or two vehicles to clear the intersection before proceeding from a stop. Delay of 10 to 20 seconds. More vehicles stop than with LOS A, but many drivers still do not have to stop. C Delay of 15 to 25 seconds. Acceptable gaps in traffic are less frequent, and drivers may approach while another vehicle is already waiting to exit the side street. Delay of 15 to 25 seconds. Drivers will enter a queue of one or two vehicles on the same approach, and wait for vehicle to clear from one or more approaches prior to entering the intersection. Delay of 20 to 35 seconds. The number of vehicles stopping is significant, although many still pass through without stopping. D Delay of 25 to 35 seconds. There are fewer acceptable gaps in traffic, and drivers may enter a queue of one or two vehicles on the side street. Delay of 25 to 35 seconds. Queues of more than two vehicles are encountered on one or more approaches. Delay of 35 to 55 seconds. The influence of congestion is noticeable, and most vehicles have to stop. E Delay of 35 to 50 seconds. Few acceptable gaps in traffic are available, and longer queues may form on the side street. Delay of 35 t o 50 seconds. Longer queues are encountered on more than one approach to the intersection. Delay of 55 to 80 seconds. Most, if not all, vehicles must stop and drivers consider the delay excessive. F Delay of more than 50 seconds. Drivers may wait for long periods before there is an acceptable gap in traffic for exiting the side streets, creating long queues. Delay of more than 50 seconds. Drivers enter long queues on all approaches. Delay of more than 80 seconds. Vehicles may wait through more than one cycle to clear the intersection. Reference: Highway Capacity Manual, Transportation Research Board, 2000 Traffic Operation Standards The City of Santa Rosa's adopted Level of Service (LOS) Standard is contained in Santa Rosa General Plan 2035. Standard TD-1 states that the City will try to maintain a Level of Service (LOS) D or better along all major corridors. Exceptions to meeting this standard are allowed where attainment would result in significant environmental degradation; where topography or environmental impacts make the improvement impossible; or where attainment would ensure loss of an area's unique character. Although the City’s standard does not specify criteria for intersections, for the purposes of this study a minimum operation of LOS D for the overall operation of signalized intersections was applied for the short-term conditions analysis. Existing Conditions The Existing Conditions scenario provides an evaluation of current operation based on existing traffic volumes during the p.m. and Saturday midday peak periods. This condition does not include projectgenerated traffic volumes. Volume data was collected for the majority of the intersections in October 2011, though Steele Lane/County Center Drive-Illinois Avenue and Cleveland Avenue/Coddingtown Drive were counted in February 2012. Counts during both time periods were taken while local schools were in session.

The project includes a 143,487 square foot Target store with a grocery section. As part of the project, 46,754 square feet of space currently occupied by small shops as well as the 154,877 anchor building will be demolished. It is understood that approximately 95 percent of the small shop space (or 44,416 square feet) as well as about 30,000 square feet of the anchor building were occupied during the time when existing count data were obtained, resulting in the loss of 74,416 square feet of space that was generating trips when the traffic counts were taken. The proposed project site plan is shown in Figure 1.

This standard reference is used by jurisdictions throughout the country, and is based on actual trip generation studies performed at numerous locations in areas of various populations. Land Use Categories Because the proposed Target store will be part of a shopping center, the net increase in floor space could reasonably be used to estimate the change in trip generation associated with the project. However, to provide a more conservative estimate of the potential change in trip generation between the loss of existing space in the shopping center and its replacement with a Target, the rates for a FreeStanding Discount Superstore were instead applied to the Target space to provide worst-case conditions. Following are excerpts from Trip Generation describing land use categories used in the trip generation estimate for this project. Free-Standing Discount Superstore (Land Use 813) – The discount superstores in this category are similar to the free-standing discount stores described in Land Use 815 with the exception that they also contain a full-service grocery department under the same roof that shares entrances and exits with the discount store area. The stores usually offer a variety of customer services, centralized cashiering and a wide range of products. They typically maintain long store hours seven days a week. The stores included in this land use are often the only ones on the site, but they can also be found in mutual operation with a related or unrelated garden center and/or service station. Source: Trip Generation, 8th Edition, page 1375 Shopping Center (Land Use 820) – A shopping center is an integrated group of commercial establishments that is planned, developed, owned and managed as a unit. A shopping center’s composition is related to its market area in terms of size, location and type of store. Shopping centers also provide on-site parking facilities sufficient to serve their own demands. Many shopping centers, in addition to the integrated unit of shops in one building or enclosed around a mall, include output parcels (peripheral buildings or pads located on the perimeter of the center adjacent to the streets and major access points). These buildings are typically drive-in banks, retail stores, restaurants, or small offices. Source: Trip Generation, 8th Edition, page 1497 According to ITE, superstores have a higher average trip rate than discount stores during the a.m. peak, and discount stores have a higher average rate than superstores during the p.m. peak. Trip Generation, 8th Edition, contains data from 92 additional trip generation studies of Free-Standing Discount Superstores compared with the 7th Edition. This substantial increase in data further validates the accuracy of the trip rates for the Free-Standing Discount Superstore (Land Use 813), which in previous editions was a newly regarded land use type. The Shopping Center land-use rates were applied to the small shops that are proposed to be demolished as part of the project. Because the rates for a shopping center are based on formulas that use the total square footage of the center, and the larger the space the lower the trip rate, the applied rates were calculated using the total size of the shopping center rather than the space being eliminated. Note that since the Gottschalk’s store was only partially occupied at the time when the counts were taken, the adjustment made to the trip generation to account for its demolition reflects this existing use in October 2011. Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 17 Pass-by Trips Pass-by trips are made as intermediate stops on the way from an origin to a primary trip destination without a root diversion. Pass-by trips are attracted from traffic passing the site on an adjacent street that offers direct access to the generator. Therefore, these trips are drawn from existing traffic so are not considered new trips. However, pass-by trips do result in additional turning movement volumes at the project driveways. Though there is no pass-by trip data for a Free-Standing Discount Superstore, pass-by reductions were made based on “Free-Standing Discount Store” (LU #815), as the major difference between land uses is the presence of a grocery section. Based on data contained in the Trip Generation Handbook, an ITE Recommended Practice, 2nd Edition, Free-Standing Discount Superstores and Shopping Centers have average pass-by rates of 17 to 21 percent for both the p.m. and Saturday midday peak hours respectively. These assumptions were applied in both the Baseline and Future traffic analyses. Diverted Linked Trips Diverted linked trips are trips that are attracted from the traffic volume on roadways within the vicinity of the generator but that require a diversion from that roadway to another roadway to gain access to the site. These trips could be on highways or freeways adjacent to the generator, but without direct access to the generator. Diverted linked trips add traffic to streets adjacent to a site, but may not add traffic to the area’s major travel routes. Using data from the Trip Generation Handbook for the Free-Standing Discount Superstore and Shopping Center uses, pass-by plus diverted link percentages were evaluated for similar sized commercial projects and relatively similar adjacent street traffic volumes. These data indicate that approximately 35 percent of the trips during the weekday p.m. and weekend midday peak hours would be diverted from the adjacent highway, US 101 in this case. Based on directional flow it was assumed that about half of this diversion (17.5 percent each) would come from US 101 south and north. These assumptions were applied in both the Baseline and Future traffic analyses by adding this portion of the project generated vehicle trips to the access driveways, local access routes such as Steele Lane and Guerneville Road, and the freeway on and off ramps; but not the mainline freeway. Internal Capture Internal capture is the reduction applicable to the vehicle trip generation for individual land uses within a multi-use site to account for internal trips between land uses at the site. For example, when an integrated land use development includes both commercial and residential uses, trips between the two uses may occur on foot, thereby reducing the potential vehicle trips. The Trip Generation Handbook provides a methodology for determining an internal capture rate for various combinations and sizes of multi-use developments. Since there is not a residential component located within the Coddingtown Mall no internal capture reduction was applied though there are likely to be trips to the Target store that are linked to shopping at the Mall as well as planned future residential development on the northwest corner of Cleveland Avenue/Edwards Avenue, just southeast of the shopping center site. By not using any internal capture, the resulting analysis is more conservative. Trip Generation Summary Summaries of the Project’s anticipated trip generation for weekdays and Saturdays are shown in Table 5 and Table 6 respectively. The project, including demolition of the some currently occupied small shops as well as the Gottschalk’s, a portion of which was occupied when the traffic counts were taken, is expected to increase average weekday traffic by approximately 1,818 daily trips from existing levels, Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 18 including 138 added trips during the p.m. peak hour. On Saturdays, the project is estimated to add an average of 2,018 new trips per day, with 156 occurring during the midday peak hour.

Trip distribution assumptions for the Station Area Plan were based on a “Select Zone” model run for a traffic analysis zone within the study area that contained primarily non-residential Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 19 land uses. The model-generated distribution of trips was combined with knowledge of the roadway network and consideration of current traffic patterns to determine the anticipated distribution of traffic associated with the proposed Target store.

This is also true for the intersection of West Steele Lane/Illinois Avenue-County Center Drive during the weekend midday peak hour. While this is counter-intuitive, this condition occurs when a project adds trips to movements that are currently underutilized or have delays that are below the intersection average, resulting in a better balance between approaches and lower overall average delay. The conclusion could incorrectly be drawn that the project actually improves operation based on this data alone; however, it is more appropriate to conclude that the project trips are expected to make use of excess capacity, so drivers will experience little, if any, change in conditions as a result of the project. Finding: The 13 study intersections would be expected to continue operating acceptably at the same levels of service upon the addition of project-generated traffic. Impacts are similarly expected to be imperceptible at the intersections of Edwards Avenue with Range Avenue and Cleveland Avenue based on the results indicated for the Jennings Avenue intersections. Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 24 Future Conditions Planned Improvements The following roadway improvements are listed in the General Plan and the City of Santa Rosa’s Capital Improvement Program (CIP), and were assumed to be complete in the evaluation of the Future conditions analysis. • • • College Avenue Widening – Cleveland Avenue to Morgan Street (Project #1153, funded for year 2013) – Widen College Avenue to provide three westbound through lanes plus bicycle lanes in both directions Install single lane roundabout at Range Avenue/Jennings Avenue Guerneville Road-Steele Lane Corridor Improvements: o Extend the right turn lane on the US 101 southbound off-ramp to a length of 250 feet o At the intersection of Steele Lane/Cleveland Avenue, reallocate the lanes on the northbound approach to Steele Lane to include separate left-turn, through, and right-turn lanes; on the southbound approach add a 100-foot long right turn lane and reallocate the remaining lanes to provide one through and two left-turn lanes; modify the intersection phasing to provide rightturn overlaps and protected left-turn phasing on both Cleveland Avenue approaches Trip Generation The trip generation estimate used to evaluate Existing plus Project conditions included a deduction for only that portion of the space to be demolished that was occupied and generating trips at the time when traffic counts were taken. In evaluating Future conditions, the General Plan EIR analysis included trips associated with build-out of (i.e. full occupation of the existing space at) Coddingtown Mall. As shown in Table 9 and Table 10, with all of the space to be eliminated by the project taken into account, the project is expected to result in a net decrease in trips during both the weekday evening peak hour and Saturday midday peak hour compared to what was evaluated in the General Plan EIR. Table 9 Weekday Trip Generation Summary (Future Conditions) Land Use Size Weekday Rate Trips In Out 318 156 162 618 303 315 -1,326 -130 -64 -66 Subtotal (Net New Trips) 4,986 488 239 249 Net New Trips (Total for Project) -1,327 -171 -84 -87 Target Store Trips PM Peak Hour Rate 3,659 All Demolished Space Shopping Center 201.631 ksf Pass by -21% 31.30 6,312 3.07 Note: ksf = thousand square feet Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 25 Table 10 Saturday Trip Generation Summary (Future Conditions) Land Use Size Saturday Rate Trips In Out 388 194 194 797 414 383 1,725 -167 -87 -80 Subtotal 6,491 630 327 303 Net New Trips (Total for Project) -2,078 -242 -133 -109 Target Store Trips Midday Peak Hour Rate 4,413 All Demolished Space Shopping Center 201.631 ksf Pass by -21% 40.75 8,216 3.95 Note: ksf = thousand square feet Because the project results in fewer trips under future conditions than would be expected with reoccupation of the existing shopping center space, it can be concluded that the project will have a beneficial contribution tofuture operation as reported in the Santa Rosa General Plan 2035 Draft Environmental Impact Report, March 2009. Finding: The project results in fewer trips than would be expected to occur with re-occupation of the existing store space on the site. The project therefore has a beneficial impact on future traffic operation because it results in decreased anticipated future volumes. Potential Future Operation with North San Rosa Station Area Plan o Because the study area for this analysis is contained within the study area used for the Traffic Impact Study for the North Santa Rosa Station Area Plan, December 9, 2011, the project’s potential to affect the results presented in this report were also evaluated. As noted, the project results in a net decrease in trips compared to re-occupation of the existing space, so the Station Area traffic study’s conclusion that acceptable operation can be achieved during the weekday evening peak hour would be unchanged by the project as proposed. However, since under Existing plus Project conditions some intersections experienced worse operation during the weekend midday peak hour than the p.m. peak hour, further analysis was performed to determine if acceptable operation would be expected with the probable growth in traffic volumes and planned future improvements. The Traffic Impact Study for the North Santa Rosa Station Area Plan contains a number of recommendations for roadway improvements as well as changes that emphasize other modes of travel to reduce reliance on auto for all travel. Because these improvements are necessary to achieve acceptable operation under Future weekday p.m. peak hour conditions, they were assumed to be complete in preparing the evaluation of Future operation during the Saturday midday peak hour. Note that some of these are programmatic in nature, while others are for specific physical improvements. • Define new standards for “Complete Street” corridors, including Range Avenue-Frances Street; common elements of the Complete Streets include: o Emphasis on multi-modal circulation o Single 11-foot wide vehicular travel lanes in each direction, 5- to 6-foot wide bicycle lanes, and 11-foot wide sidewalk/planter areas with landscaping (one exception to the single vehicular through lanes would be on Range Avenue between a point about 200 feet north of West Steele Lane and Guerneville Road where two southbound lanes would be needed to provide capacity) Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 26 12-foot wide center turn lane or median in some locations (raised medians, when used, would include 2-foot offsets from adjacent travel lanes) Implement a grid pattern of streets o Complete two new north-south streets in the area south of Coddingtown Mall between the Range-Frances corridor and Cleveland Avenue in order to create a grid network Guerneville Road-Steele Lane Corridor Improvements o Construct a 100-foot long right-turn lane on westbound Steele Lane at the US 101 northbound ramps intersection Cleveland Avenue Improvements o Consider adding landscaped medians between College Avenue and Coddingtown Mall, and consider eliminating one southbound vehicle lane on between Coddingtown Mall and Frances Street to provide space for bicycle lanes or striped shoulders on both sides of the street o • • • Projected future traffic volumes for the weekday p.m. peak hour and the associated operational results were obtained from the Traffic Impact Study for the North Santa Rosa Station Area Plan . These volumes were used to evaluate operation at the 13 study intersections as a baseline against which to compare weekend operation. It should be noted that the Station Area traffic study used a corridor Level of Service methodology, which is consistent with the City’s Level of Service standard and operational results presented in the General Plan DEIR. However, because the Station Area traffic study included a larger study area, the corridors studied were considerably longer than the short segments connecting the study intersections for this analysis, so a direct comparison was not reasonable. The corridor methodology is based on running time for an entire corridor, and as a result, some intersections are expected to operate at lower Levels of Service (LOS E or F), but because the remainder of the corridor is operating more smoothly, the overall operation is considered acceptable. The LOS results obtained for individual intersections were therefore not used to evaluate this scenario directly as some are below the LOS D standard; instead they were used as a point of comparison for the Saturday midday peak hour, assuming that if the intersections are all operating at lower delays on Saturdays than during the weekday p.m. peak, the corridors will be operating as well as or better than projected for the p.m. peak hour. A factor was determined for the increase in traffic during the Saturday midday peak hour by comparing the trip generations for the land uses in the Station Area Plan analysis for the Saturday midday peak hour and the p.m. peak hour. Total trips for each peak hour were determined based on the projected land uses and densities, and the ratio of these future trips used together with the difference between existing and future volumes for the p.m. peak hour to escalate current Saturday midday peak hour volumes to future volumes. A copy of the spreadsheet showing the trip generation data and resulting growth factors for each intersection is provided in Appendix C. The 13 study intersections were analyzed under both projected p.m. peak hour and Saturday midday peak hour traffic volumes. From this analysis, it was determined that all 13 study intersections are expected to operate better under Saturday peak hour traffic volumes than under p.m. peak hour traffic volumes. It is therefore concluded that traffic operation with weekend midday peak hour traffic volumes will be as good as or better than weekday p.m. peak hour operation, which was determined to be acceptable in the Traffic Impact Study for the North Santa Rosa Station Area Plan with implementation of improvements identified in the traffic study. Finding: The analysis of Future Conditions as reported in the Traffic Impact Study for the North Santa Rosa Station Area Plan indicates that acceptable operation of the corridors on which the study intersections are located can be expected with implementation of planned and recommended improvements. The project will contribute to improved operation by generating fewer trips than would have occurred if the existing development was re-occupied. Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 27 Alternative Modes Pedestrian Existing sidewalks, curb ramps and marked crosswalks are provided at intersections surrounding the project site. Sidewalks also exist along the perimeter of existing buildings on the Coddingtown Shopping Center site and would be extended to provide full connectivity of pedestrian facilities serving the proposed new Target building and the existing shopping center. Finding: Existing and proposed pedestrian facilities in the vicinity of the project are expected to adequately serve the project. Bicycle A variety of existing bikeways are provided in the vicinity of the project facilitating both north-south and east-west access. Further, a regional Class I multi-use pathway is planned along the SMART Rail, a bicycle and pedestrian bridge over US 101, and several local bikeways are planned along adjacent streets and off-street corridors, all of which will increase access options for bicyclists in the future. The preferred alignment for the bicycle and pedestrian bridge over US 101, which would connect Elliot Avenue on the east side of US 101 to Coddingtown on west side, consists of a 14-foot wide “commuter linkage” that runs directly through the Coddingtown Mall parking lot south of the proposed Target store. Finding: Existing and planned bikeways in the vicinity of the proposed project will provide a variety of access options for bicyclists traveling to and from the project site. Transit The project is located within a short walking distance of the transit hub at Coddingtown, which is served by CityBus Routes 7, 10, 11 and 15, so the site is accessible via transit. It is anticipated that future transit demand generated by the project could be accommodated by the existing transit routes as well as the SMART train. The Northwest Santa Rosa Station will be located about one-half mile from the Target store, so could serve both employees and customers. Finding: Existing and planned future transit services are expected to adequately serve the project site. Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 28 Access and Circulation Site Access Access to the project site will be via existing driveways on Range Avenue, Guerneville Road, Cleveland Avenue, and Edwards Avenue. The project site is located in the middle of the shopping center site, and does not affect any existing driveways. Since no changes are anticipated, the project has no impact on the adequacy of existing site accesses. Further, since the project results in a lower trip generating potential than would be expected with re-occupation of the existing shopping center space, operation of the existing driveways will be positively impacted by the reduced traffic demand. On-Site Circulation The proposed Target building will be located in an area currently occupied by a large, anchor tenant building, but because of its smaller footprint, the project will result in a change to the parking pattern just south of the building. The existing east-west parking aisles will be replaced with north-south aisles, so will match the pattern of the parking fields surrounding this area. This change will improve circulation through the parking lot as all of the parking aisles in the area south of the shopping center will be in the same direction. No other changes to the site’s existing circulation patterns are expected as a result of the project. Finding: The project results in no changes to site access, and improves site circulation by re-orienting the parking field south of the project building to match the fields surrounding it. Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 29 Parking Adequacy of the parking supply for the project was evaluated based on the Santa Rosa City Code, Title 20: Zoning Ordinance; Section 20-36.040, which states that, “each principally or conditionally permitted use shall provide at least the minimum number of off-street automobile parking spaces.” Because the project will be part of a larger development that shares parking with the proposed use, the parking demand was calculated for the entire Coddingtown site. The City requires one parking space for each 250 square feet of general retail and office development. Evaluating these uses individually and assuming full capacity of each use, 3,424 spaces are required for the combined total of 825,363 square feet of retail space and 30,520 square feet of office space. The site plan shows a total of 3,323 proposed parking spaces, which is deficient by 101 parking spaces based on application of City standards. Since direct application of the City’s parking requirements indicates a deficiency, further analysis was performed to determine the potential for parking to be shared by the existing and proposed uses and the resulting peak parking demand. The Urban Land Institute (ULI) publication Shared Parking, 2nd Edition, 2005, includes state-of-thepractice methodologies for determining parking demand in an environment where different types of uses share a common parking facility or area. The ULI shared parking methodology focuses heavily on temporal data, determining when the overall peak demand for various land uses would occur, including what time of day, whether it is a weekday or weekend, and what month of the year. The recommended parking supply is then tied to that maximum demand period. The base input data includes the proposed mix of land uses and quantities of each type of use. The methodology then requires the input of “mode adjustment” and “non-captive ratio” values. Mode adjustments are applied to the default parking demand ratios, which are based on auto-oriented suburban developments, to reflect conditions where auto ownership is expected to be lower, transit usage higher, and other non-automobile modes of travel such as walking and bicycling higher. Several elements need to be considered when determining vehicle ownership trends for transit-oriented urban areas such as that envisioned for the Station Area surrounding the project site. A Caltrans-funded study (Travel Characteristics of Transit-Oriented Development in California, 2005, Lund, Cervero, and Willson) indicates that vehicle ownership at California TODs has been found to decrease over time as density and transit service increase. The July 2006 publication MTC’s Resolution 3434 Transit-Oriented Development Policy: Interim Evaluation indicates that the average automobile ownership at transit station area developments in California is 1.4 vehicles per household. This is 26 percent lower than the 1.9 vehicles per household reported for the central Sonoma County area in the 2005 Metropolitan Transportation Commission (MTC) data summary publication Vehicle Ownership Forecasts for the San Francisco Bay Area: 1990-2030 (November 2005). Over time as the study area experiences increasing TOD activity, it is expected that vehicle ownership (and the total number of vehicles owned per household) will decrease and the number of trips made by walking or bicycling will increase. Separate mode adjustment factors can also be made for employees within the study area. Travel mode data for Santa Rosa employees obtained from the 2000 Census Transportation Planning Package (CTPP) “Journey to Work” tabulations indicate that 83 percent of all home-to-work trips in Santa Rosa are completed in single-passenger private autos, 12 percent regularly carpool, 2 percent by transit, and 3 percent walk or bicycle. These statistics are very similar to more recent data for Sonoma County overall in the year 2006, as shown in MTC’s Data Summary publication Travel Forecasts for the San Francisco Bay Area: 2009 Regional Transportation Plan: Vision 2035 Analysis (November 2007). This data Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 30 was used to develop appropriate automobile usage assumptions when adjusting employee travel modes in Santa Rosa. The non-captive ratio adjustments in the Shared Parking methodology are based on the concept of a “captive market,” which refers to customers who visit more than one establishment or type of land use without making a separate trip, or in this case, parking their vehicle more than once. This can also apply to employees in a core environment who park in a garage or at work, but visit nearby businesses during breaks or at lunchtime. Using the methodology established by ULI, it was determined that the existing and proposed uses at the would be expected to generate a peak shared parking demand of 3,183 parking spaces at 2:00 p.m. during a weekend day in December at the Coddingtown Mall. The projected peak parking demand on weekdays is 2,937 parking spaces at 2:00 p.m. in December. The proposed parking supply of 3,323 spaces would therefore be sufficient during weekday and weekend peak conditions. Calculations indicating the ULI shared parking demand rates for both weekdays and weekends are included in Appendix D. Finding: The proposed parking supply of 3,323 spaces does not meet the City parking requirements of 3,424 parking spaces, but does meet ULI’s projected shared peak parking demand of 3,183 parking spaces. Recommendation: In order to avoid having more parking at the site than is needed, even under anticipated peak conditions, it is recommended that the City accept the shared parking analysis and proposed parking supply through approval of the Conditional Use Permit. Traffic Impact Study for the Coddingtown Target in the City of Santa Rosa April 18, 2012 Page 31 Conclusions and Recommendations Conclusions • Compared to Existing conditions with partial occupation of the spaces slated for demolition, the proposed project is expected to result in a net increase of 1,818 weekday vehicle trips, which includes 138 net new trips during the p.m. peak hour, and a net increase of 2,018 weekend vehicle trips, which includes 156 net new trips during the weekend midday peak hour. • Demolition of the Gottschalk’s anchor building and some existing space on the south side of the mall and replacing it with a Target Store having less square footage than what is being replaced is expected to result in a net decrease of 1,327 weekday vehicle trips, including 171 fewer trips during the p.m. peak hour, and a net decrease of 2,078 weekend vehicle trips, with 242 fewer trips during the weekend midday peak hour. • All 13 of the study intersections are currently operating acceptably and are expected to continue operating acceptably with the addition of trips from the proposed project. • With two exceptions, the study intersections are experiencing collisions at lower-than-average rates. Above average rates were experienced during the study period at Guerneville Road/Range Avenue and Steele Lane/US 101 North Ramps. The incidence of crashes at the Steele Lane/US 101 North Ramps intersection has decreased since completion of the US 101 widening project, so this increased capacity appears to have had a positive effect on safety. • Under Future Conditions, as modeled for the Station Area Specific Plan DEIR, the street network in the study area is expected to continue operating acceptably during the p.m. peak hour. Analysis performed indicates that acceptable operating conditions for the corridors surrounding the site will also be maintained during the weekend midday peak hour. • Pedestrian facilities in the vicinity of and throughout the project site are expected to adequately serve the project. • A number of existing and planned bicycle facilities are available near the project site; however, the proposed project appears to be inconsistent with the Station Area Plan as it does not show the “commuter linkage” segment of the bicycle and pedestrian bridge project. • Existing transit routes are within an acceptable walking distance of the project. • No changes to site access are proposed. Minor changes to the parking field orientation south of the project site are expected to improve site circulation. • Direct application of the City of Santa Rosa’s parking standards results in a requirement for 3,424space parking requirement. The proposed supply of 3,323 spaces would fall short of this by 101 spaces. Application of the methodology established in ULI’s shared parking model results in a peak parking demand of 3,183 spaces, which is fewer spaces than are proposed. Based on the shared parking analysis, it appears that the parking supply as proposed is adequate. Recommendations • It is recommended that the City accept the shared parking analysis and allow the parking supply as proposed through approval of the Conditional Use Permit.
